I do think that we should have a system that automatically verifies
that all public header files compile by themselves, but any #includes
beyond what's needed to compile the header itself are not desirable. I
specifically don't want any #includes that are not needed until a
template is instantiated.

If we have an automatic header test, I'd like it to attempt to remove
#includes until it finds the minimum needed to compile the file,
because I'm sure we have many #includes that perhaps were needed
before but are no longer necessary.
