-Before 2.0
-    Get Documentation fixed and completed
-
-1.6
-    Iterator move and move_to
-    from_array - Creates a collection with all the elements in a specified array
-    to_array - Creates an array with all the elements inside the collection
-    LinkedList - Insert/Remove/Append/Prepend/Extract
-    Resize buffer function
-    Add dispose method to each collection in order to automatically free its data
-    Add copy functions (copy of a collection)
-
-2.0
-    Add new heap collection implementation
-    Add all stack based collections
-
-2.1
-    Add variadic macros (generate only the necessary functions)
-
-2.2
-    Add serialization functions
-
-2.3
-    Iterator functions (functions that operate relative to iterators position) like add or remove ranges
-
-SOMETIME
