+     as unit tests will fail.
+
+    Note:
+     a) `list_obtain` shall allocate only the list data, but NOT the payload buffer
+     b) The payload buffer shall be allocated when a value is inserted the first time.
+        The payload buffer shall be increased if an additional item shall be inserted 
+        (via one of the insert functions) no capacity is left. All  values contained in the list
+        shall be copied into the increased buffer.
+        Initial allocation of the payload buffer and increasing the payload buffer is actually
+        the same case, because the initial capacity is 0 and therefore no capacity is left.
+        The payload buffer shall be increased by `CAPACITY_INCREMENT` (`config.h`) items.        
+     c) `list_clear` shall NOT free the payload buffer. Setting the size to 0 is sufficient.
+     d) `list_release` shall free the payload buffer, if it was allocated.
+
+  3) Use 'limits.h' to get maximum and minimum values for numeric types, if needed.

+Introduction</h1>
+<p>The implementation and evaluation of a collection of Sorting and Searching Algorithms.</p>
+<h1><a class="anchor" id="objective"></a>
+Assignment Objective</h1>
+<p>The target collection those algorithms are operation on, is an 'Array Backed List'. This list shares (almost) the same interface (<code>list.h</code>) as the linked list from previous assignments but is implemented based on an array. Different sorting and searching algorithms are to be implemented using that list. A stopwatch shall be implemented that is used to measure the time a certain algorithm requires to sort or search. Eventually the measured times for defined number of list items and algorithms are compared.</p>
+<p><b>Configuration</b></p>
+<p>The capacity of the backing array of the list is defined in <code>config.h</code> as <code>#define CAPACITY_INCREMENT</code>. This value defines also the number of items for enlarging the backing array. This means, the array grows always in steps of <code>CAPACITY_INCREMENT</code> items.</p>
+<h1><a class="anchor" id="assignment"></a>
+Assignment</h1>
+<p>In this assignment various sorting and search algorithms shall be implemented in multiple steps.</p>
+<p><b>Step 1:</b></p>
+<p>Implemenation of an 'Array Backed List' by implementing files <code>array_backed_list.h</code>. This file implements <code>list.h</code> using an array as underlying collection instead of a linked list. In contrast to earlier assignments, the function <code>list_append(…)</code> was removed and <code>list_swap(…)</code> was added. The array shall have a certain capacity and need to be increased (with all consequences, such as of copying items) if another item is added to a 'full' list. As a benefit, random access to items is fast, which is required by (most) sorting and searching algorithms. For implementation details read and follow the instructions in file <code>array_backed_list.c</code>.</p>
+<p><b>Step 2:</b></p>
+<p>Implementation of the infrastructure for selecting and using sorting and searching algorithms as well as for measuring the time a certain algorithm takes for completing its operation.</p>
+<p><b>Step 3:</b></p>
+<p>Implemenation of the following sorting algorithms:</p><ul>
+<li>- TO BE DEFINED &ndash;</li>
+</ul>
+<p>The library 'allocator' is provided for memory allocation functionality that integrates with unit testing. Behind the facade, allocats memory dynamically similar to <code>malloc</code>. Allocated memory must be freed when it is not used anymore. The 'allocator' library must be used for memory alloction operations, otherwise unit tests will fail.</p>
+<ol type="1">
+<li>Implement 'array_backed_list.c' against interface indirectly declared in 'list.h': Make the program and tests compile: Implement all functions in all relevant files declared in the headers EMTPY (return nothing, 0, false, ... as required).<ul>
+<li>All unit tests shall run but FAIL after this step</li>
+<li><b>&ndash;COMMIT&ndash;</b></li>
+</ul>
+</li>
+<li>Implement the empty functions one by one to make the unit tests.<ul>
+<li>Because most unit tests depends on <code>list_obtain(…)</code>, <code>list_release(…)</code>, <code>list_is_valid(…)</code>, <code>list_is_empty(…)</code>, <code>list_insert(…)</code>, and <code>list_get_size(…)</code> it makes sense to implement those functions in one step.</li>
+<li>The purpose of a function is specified as API documentation within the header files.</li>
+<li>Obey comments in source files. Run the unit tests frequently and fix failures.</li>
+<li><b>&ndash;COMMIT&ndash; after each implemented function.</b></li>
+</ul>
+</li>
+</ol>
+<h1><a class="anchor" id="notes"></a>
+Notes</h1>
+<ol type="1">
+<li>make cleantest: This new make target for clearing the console, building, and running unit test is available.</li>
+<li>Sometimes changes are not properly detected by incremental builds. If something very strange happens during compilation, try to run <code>make clean</code> followed by <code>make</code> to start a clean build. This approach is also recommended after everthing is done, because some compiler warning appears only in clean builds. </li>

+/**
+* @mainpage
+* @section intro Introduction
+*
+* The implementation and evaluation of a collection of Sorting and Searching Algorithms.
+* 
+* @section objective Assignment Objective
+*
+* The target collection those algorithms are operation on, is an 'Array Backed List'. 
+* This list shares (almost) the same interface (`list.h`) as the linked list from previous assignments
+* but is implemented based on an array.
+* Different sorting and searching algorithms are to be implemented using that list.
+* A stopwatch shall be implemented that is used to measure the time a certain algorithm requires to sort or search.
+* Eventually the measured times for defined number of list items and algorithms are compared.
+* 
+* **Configuration**
+*
+* The capacity of the backing array of the list is defined in `config.h` as `#define CAPACITY_INCREMENT`. 
+* This value defines also the number of items for enlarging the backing array. This means, the array grows
+* always in steps of `CAPACITY_INCREMENT` items.
+*
+* @section assignment Assignment
+*
+* In this assignment various sorting and search algorithms shall be implemented in multiple steps.
+*
+* **Step 1:**
+*
+* Implemenation of an 'Array Backed List' by implementing files `array_backed_list.h`. 
+* This file implements `list.h` using an array as underlying collection instead of a linked list. 
+* In contrast to earlier assignments, the function `list_append(…)` was removed and `list_swap(…)` was added.
+* The array shall have a certain capacity and need to be increased (with all consequences, such as of copying items) 
+* if another item is added to a 'full' list.
+* As a benefit, random access to items is fast, which is required by (most) sorting and searching algorithms.
+* For implementation details read and follow the instructions in file `array_backed_list.c`.
+*
+* **Step 2:**
+* 
+* Implementation of the infrastructure for selecting and using sorting and searching algorithms as well as
+* for measuring the time a certain algorithm takes for completing its operation.
+*
+* **Step 3:**
+*
+* Implemenation of the following sorting algorithms:
+* - - TO BE DEFINED --
+*
+*
+* The library 'allocator' is provided for memory allocation functionality that integrates with unit testing. Behind the facade,
+* allocats memory dynamically similar to `malloc`. Allocated memory must be freed when it is not used anymore. The 'allocator'
+* library must be used for memory alloction operations, otherwise unit tests will fail.
+* 
+*
+* -# Implement 'array_backed_list.c' against interface indirectly declared in 'list.h':
+*    Make the program and tests compile: Implement all functions in all relevant files declared in the headers 
+*    EMTPY (return nothing, 0, false, ... as required).
+*   - All unit tests shall run but FAIL after this step
+*   - **--COMMIT--**
+* -# Implement the empty functions one by one to make the unit tests.
+*   - Because most unit tests depends on `list_obtain(…)`, `list_release(…)`, `list_is_valid(…)`, 
+*     `list_is_empty(…)`, `list_insert(…)`, and `list_get_size(…)` it makes sense to implement those
+*     functions in one step.
+*   - The purpose of a function is specified as API documentation within the header files.
+*   - Obey comments in source files. Run the unit tests frequently and fix failures.
+*   - **--COMMIT-- after each implemented function.**
+*
+*
+* @section notes Notes
+* -# make cleantest: This new make target for clearing the console, building, and running unit test is available.
+* -# Sometimes changes are not properly detected by incremental builds. If something very strange 
+*    happens during compilation, try to run `make clean` followed by `make` to start a clean build.
+*    This approach is also recommended after everthing is done, because some compiler warning appears
+*    only in clean builds.
