actionDictionary

Action Dictionary. This is a lookup table that we generate during preinit from the vocabulary words associated with 'predicate' grammar rules. We map each vocabulary word to the Action objects it's associated with.

The standard dictionary contains all of these words as well, but it maps them all to the generic 'predicate' GrammarProd object. That doesn't help us identify which words are associated with which actions. That information is sometimes needed, such as during spelling correction.

Note that the system library file gramprod.t must be included in the build, so that GrammarAltInfo is defined.

word-to-action table: this maps each vocabulary word to a list of the Action objects associated with the grammar rules in which it appears

Associated word table: this maps each vocabulary word to a list of all of the other words that appear in predicate grammar rules in which the given word appears. For example, 'up' will have a list like [pick, go, look], since it's used in rules for 'pick up', 'go up', 'look up'.
