/* Initializes a graph connecting (state, production item) pairs to
pairs they can make a transition or production step to. This graph
pairs they can make a transition or production step to. This graph
is used to search for paths that represent counterexamples of some
conflict.
state_items is an array of state state-item pairs ordered by state.
state_item_map maps state numbers to the first item which
corresponds to it in the array. A state's portion in state_items
begins with its items in the same order as it was in the
state. This is then followed by productions from the closure of the
state in order by rule.
