[gatest] Add basic geometric algebra test This is for developing methods of implementing geometric algebra and eventually playing with it visually.

[gatest] Write a simple parser for playing with GA Currently only PGA(3) is supported, but that's because the parser is rather simple (recursive descent with a lame lexer), but it works well enough for playing with geometric algebra without having to recompile every time.

-(MultiVector *) dual;
[gatest] Implement and use multi-vector reverse This gives the resultant point the correct sign. Though the projective divide would take care of the sign, this makes reading the point a little less confusing (still need to sort out automatic blade reversals for the likes of e31).
