MCT 1.4

Written for MCT by Paul Pogonyshev on 2011-07-14

Stable MCT 1.4.0 is released. There are no major new features, but rather a large set of memory footprint and performance optimizations and several minor additions, like quick_erase() method. Empty hash tables now don't use any dynamic memory, which makes them more suitable for "many tables, many of them empty" use case. Documentation now lists complexity for all functions and test collection grew by a half.
