/** @descr
|

This state-machine models state transitions from one state to another
|
|
per indices of branches. If the indices represent ascii-char-values,
|
|
the state-machine can be used for recognising tokens of text.
|
|
|
|
The state-machine can be a status itself.
|
|
|
|
StateMachin2 needs the array-size of all stati as a guess, how many stati
|
|
the state machine will contain, when at work.
