This gets only some very basics working: * Algebra (multi-vector) types: eg @algebra(float(3,0,1)). * Algebra scopes (using either the above or @algebra(TYPE_NAME) where the above was used in a typedef. * Basis blades (eg, e12) done via procedural symbols that evaluate to suitable constants based on the basis group for the blade. * Addition and subtraction of multi-vectors (only partially tested). * Assignment of sub-algebra multi-vectors to full-algebra multi-vectors (missing elements zeroed). There's still much work to be done, but I thought it time to get something into git.
