- Implemented Path::operator (std::string) const, to provide an
automatic cast to std::string for any Path, File or Directory.
- Made use of new cast in various code.
- Changed use of spaces in atoi () calls.
- Switched from std::string::data () to std::string::c_str () calls.
- Merged Path, File and Directory handling objects from metatask.git.
- Merged unit tests.
- These objects will replace a fair amount of code in task 1.9 and
more in 2.0.
