#13 Add search functions & operators

[William McKee]

Add support for functions & operators (aka, symbols in
FileMaker Pro) to allow more complex searches such as
"between 12/01/2001 and 12/10/2001". These should be
simple to use (user-friendly) and will need to have
cross-db support.

I think the user-friendly FileMaker Pro is a good
candidate for the model of the language to be used in
dbEngine. Attached is a document that describes the
symbols available in FMPro. The original document (with
images) is located at
