- added interface for passing the projections to the resolution to lk transformation. Note that since the LK proof must be a tree
the projections must be cloned somehow so right now the implementation will not work if a projection is used more than once.
- creating contractions after the application of each binary rule. This is also buggy as I dont check if the contracted formula is required in the resolution proof.
The algorithm will throw an exception anyway if this is the case.
