Wink Saville a4f3bec29c Update docs, add HANDLED, NOT_HANDLED and getCurrentMessage.
The EBNF statemachine description language was to difficult
to remember changed to use a simpler and more obvious psuedo
language.

Added HANDLED and NOT_HANDLED as it makes the psuedo code
more obvious.

Added getCurrentMessage primarily for use by code in enter
so that it can know why the new state is being entered.
