[Snippet] a Recursive Descent Parser via TDD - test.h

[Phlip]

C++ newsgroupies:

I wrote a parser to solve math expressions like "3.0 ^(4 - 5)", or "3 / 8".
Below my sig is test.h, the file containing a tiny test framework. Using it
and Test-Driven Development, I produced the test suite and the parser,
appearing in parallel posts.
