Specific Project Classes

[goncaloasimoes]

We run into the problem of having the Project class handle options that can be very tool specific. So the need arises to have various Project classes which handle each specific need. The problem is how to make Config able to create each of the classes.

We could do this via a mapping of purpose and the appropriate Project Class. The problem with this is that we could have various tools for the same purpose in the future, so the mapping would have to be more complex.

But for now the purpose can be directly related to the Project class with no issues.
