We want to reuse the event grammar for parsing aliased terms. The obvious reason is we dont need to add new code when there's already support for this in event grammar. Doing this by adding terms and event start entries into event parse grammar. The grammar forks on the begining based on the starting token, which is supplied via bison interface into the lexer. The lexer then returns the starting token as the first token, thus making the grammar switch accordingly. Currently 2 starting tokens/grammars are supported: PE_START_TERMS, PE_START_EVENTS The PE_START_TERMS related grammar uses 'event_config' part of the grammar for term parsing.
