More work towards #1350 this adds support for functions from wedges. This is the the foundation of path concatenation. This also introduces wedge_prod, which is an alternative way to construct wedge products. Things like hausdorff are a lot easier to prove when viewing it as a subspace of a product, rather than a quotient of a sum (since quotients don't respect hausdorff).

In the last commit, I introduced lemmas about existT in boolp.v so that we do not need to import from the Coq standard library and use lemmas with better names. Other modifications are just linting (remove a destruct, etc.).
