allow None in param shape

[ConnorStoneAstro]

Param shape can now have None as an entry. It will take the size of that dimension from the param value if available. This allows specifying the structure of a param without specifying the exact shape. Such as requiring an entry to be an image (2D with shape (None, None)) of any size.

Looking good! Just a couple small things to clarify: does shape = None just assume no shape at all, and does shape = (None, ) assume a 1D shape?

That's right! Good point though, I'll make that clear in the docs.
