coding: size_t with sign
more work on size_t for comparsions, and to unsign
size_t versus signed integral checks [ok]?
[good] handling of size_t vs integral + testcase
[good] added reversed secure size_t comparsions
[git] ignore a.out
Using boost::cpp_int to unit test my xsize_t
size_t: explit constructor; changing the approach
size_t comparsion new. TODO [bad] <=
size_t -Werrors
add == and != operators
