A few questions about your library:
-How does one represent non-whole dimensions (such as m^1/2)?
-How do I add new dimensions (different types)?
-Will it work with non-fundamental/user-defined types, such as complex?
-Is it possible to automatically determine the type of a calculation? 
That is, I want to declare q as the type of whatever a * b / c is?

It seems like a really functional library, accomplishing its task at 
compile time (what I had hoped for in my code).  Though it seems 
extremely bulky and takes a while to compile.

By doable, what do you mean?  It is vitally important to my project that 
all this typing is turned off to allow the compiler to get a high-level 
of optimization.
