Print or log out parameter length when compiling the solver about optimization-engine

[alphaville]

Shane, that's a good point. Just note that the number of parameters is the length of the vector p, which is provided by the user. I will improve the error message as well.

@strimble08 Now the builder returns this information (in the form of a dictionary). Will this be sufficient?

Yes looks great - I can see this info in one dict being useful for more than just the initial feature I suggested.

This is now available in opengen, version 0.7.1.
