Expand description

Identifies common relation subexpressions and places them behind Let bindings.

All structurally equivalent expressions, defined recursively as having structurally equivalent inputs, and identical parameters, will be placed behind Let bindings. The resulting expressions likely have an excess of Let expressions, and therefore we automatically run the NormalizeLets transformation to remove those that are not necessary.
