A group is a special N-ary operator delineated by a left-hand symbol and a right-hand symbol, with comma-separated arguments.

Launches the console-driven expression evaluator.
A mathematical operator is a special symbol or "verb" which defines a relation between "nouns" (i.e.: literals and variables).
A collection of standard
