- prototype unit test suite based on CUnit added.
- unit tests for base/generic/general and base/generic/utilites added.
- 2nd manual rework of doxygen documentation in general and utilities.
- bug fixes (mostly general & utilities) found during test development.
- added asc_assert prototype to redirect failures to Asc_Panic() and enable decoupling assertions from NDEBUG.
- some modifications of interface & implementation to facilitate testing.
- utilities/ascPrint & utilities/ascMalloc functions now always included in base libs to minimize recompilation when an interface chooses different options.
