The files must be distinguished:
- mailbox.hxx and mailbox.t.cpp are templates for resp. the header
and the source
- mailbox-vector.h/cpp correspond to an implementation of the
template for a maal::vector. Those are the symbols exported in the
library mailbox-vector.so/.lib
- test_mailbox corresponds to the test of Mailbox<maal::vector>

Simplified the unit test test_mailbox that previously *required user input*.

Added pthread library and compilation & link flags.
Corrected multiple small bugs.
Added CMakeModules for pthread and boost numeric bindings.
Corrected some tests.

Some commands modify the compilation/linkage flags of every pkg added after.
 e.g. ADD_DEFINITIONS, INCLUDE_DIRECTORIES and LINK_DIRECTORIES.
Applying these commands in a loop FOR_EACH can create a huge and redundant list
of compilation/link flags.
Placing them before the for_each is then a cleanup operation (only): it does
not modify the flags order
