Merge pull request apple#97 from stephentyrone/prefix-modules

Enable name lookup for modules by suffixing `Module` when needed to break ambiguity.

In particular, the following module renames are applied:

- Real -> RealModule
- Complex -> ComplexModule

This is a source-breaking change, if you currently directly import these modules. (sorry!)
The fix is to either import Numerics instead, or to use the new, suffixed, names. The good news is that fixing this should require only a straightforward search-and-replace for anyone affected.
