Subject: [PATCH] Introduce 'nncc_foundation' (#93)

This commit introduces 'nncc_foundation' library which includes
functions and classes not directly related with compiler itself, but
useful when implementing it.

The initial version includes the implementation of 'make_unique' which
makes it easy to use 'std::unique_ptr'.
