c-algorithms

• The license has been changed to the ISC license.
• Support for compiling with gcc coverage options and running tests in
  valgrind.
• All headers now have extern "C" definitions for use in C++ programs.
• Trie free function uses a non-recursive algorithm to avoid the
  possibility of stack overflow.

Test suite:

• Framework added for testing memory allocation/free.
• Tests have been fixed to properly free any memory allocated during
  execution of the test.
• Tests have been expanded to increase the code coverage.
• A test case has been added for testing use of the program in C++
  programs.

Bugs fixed:

• Memory leak in hash table.
• Bugs with the AVL tree.
• Trie responds to out of memory scenarios correctly.

• Added data structures:
  • Binary Heap
  • Binomial Heap
  • Bloom Filter
• Iterator functions changed to a model based around an iterator structure
  rather than callback functions.
• Void pointers used for keys/values replaced by typedefs to void pointers.
  This allows the type to be changed to something else if desired.
• Hash table sizes changed to use a set of recommended prime numbers
  that are mathematically good for use in hash tables:

• Tests added for some code that was not covered by the test suite.
• Failed malloc() calls are now checked for.
• Bugs fixed:
  • Lockup with set_remove function.
  • set_to_array did not include all values.

First release.
