suppor create from template

template := `
1=New
2=Ready
3=Waiting
4=Running

Admitted:1->2
Dispatch:2 -> 4

InputOutputoreventwait:4->3

Exit:4->5
`

format as follow:

//for example：
action1:state1 -> state2
action2:state12-> state3
action3:state13-> state2

Great idea! Is there some accepted syntax/DSL for defining state machines that could be used instead?
