implementation of a new variant of TA, called STA, which involve a
Single-pass emptiness check. The new options (-in and -lv) added to
build the new variants of TA allow to add two artificial states:
1- an initial artificial state to have an unique initial state (-in)
2- a livelock artificial state which has no successors in order to
obtain the new form of TA which requires only a Single-pass emptiness-
check: STA (-lv).
