Tape Input

[StoneCypher]

Traditional finite state machines typically operate over a fixed input, nominally either a string or a vector of symbols. We should support that use case, ostensibly in the constructor, and/or with a .reset #449 , and/or with a direct call (the direct call is probably important for machines that need to be configured before run, but the constructor is probably the one that will mostly get used)

What this should actually do is take the inputs apart and issue them as a sequence of actions

"Bob" means machine.action('B').action('o').action('b');

• input call
• input as constructor arg
• input wrt reset
