Adding a primitive expression parser. It will parse simple

expressions such as a + b/(c+(d+f)) correctly, but mucks up
things like a+ b/c/d as it doesn't look too hard for places
to put brackets in.  A fully parenthesised expression should
be fine.

It also doesn't have good error checking.

All thing improve with time...  (well most, anyway 8-)
