Regular expressions. For Sequence and Alternative there is a choice between a body of two sub-expression or a list of sub-expressions. I choose the list because it tends to simplify the code, for example be having One and Zero RegExprs as special cases.
TODO o atoms/ranges of arbitrary bit length o default length 16; adjustable o atom ::= code [ ":" bits ] o an atom is translated into n single-bit transitions o FA.mergeTransitions(m) o compose m transitions into single transitions o caution with end states o replace range tests in TableFA by array indexing; e.g. scan char by 4x4 transitions o caution: reading from an input stream raised byte order issues o Visitor for getRanges
