new formulae language implementation

unified language and parser for the registered types  'vector' and 'real' and @dictionary parameters
referenceing of values across cps rules/@dictionaries etc
transformation matrices
Polar vector constructor
updated importer that saves onDir and onLength
got rid of a lot old code
etc.

Is this a premature optimization? Try removing the cache for now? (If it's needed later, can't you just use a memoizing wrapper?)
