Sglib 1.0.4

Sglib project is a library defining useful macros for manipulating common data structures. The library currently provides generic implementation for:
- sorting arrays
- manipulating linked lists
- manipulating sorted linked lists
- manipulating double linked lists
- manipulating red-black trees
- manipulating hashed containers
Sglib consists of a single header file without any binary code. In consequence it is absolutely platform independent. In order to use it just put #include "sglib.h" into your source code.
The library is implemented in the C programming language and written for C programmers, however it is freely inspired by the Standard Template Library.
In general, Sglib macros are parametrized by the type of the data structure and a comparator function (or comparator macro). Several further generic parameters such as the name of the next field for linked lists may be required.
Although I wish to keep the library as simple as possible all suggestions for new functionalities are welcomed. Currently, the implementation of queues, priority queues, hashed tables and AVL trees is in progress.
Enhancements:
- This release fixes problems with overflow of the numeric comparator.
