description:
Defines the tokenizer for an RPSL aggr-mtd attribute. It was mostly
stolen from the IRRToolSet, simplified by removing ability to parse
things defined by a dictionary (we use XML for extensibility rather
than a dictionary).
notes:
Tokens are defined in the associated grammar, aggr_mtd.y.
