Contract files are those extended with ``wast``, ``wasm`` and ``abi``.
First, the ``contract_file_hint`` may be an absolute path.
Next, it may be relative to the contract directory.
The contract directory is the container for the project of a contract. This
directory is determined with the ``getContractDir`` function, basing on the
``contract_dir_hint``.
Any contract directory contains directories and files structured according
to few schemes:
flat structure with all the files in this directory as in the ``eos/contracts/*`` contract directories in the EOS repository;
structure with a directory named ``build`` as resulting from the EOSFactory templates;
