/*
 * Various utilities to assist in statblock parse/conversion. Formatted as a Node module, to allow external use.
 *
 * In all cases, the first argument, `m`, is a monster statblock.
 * Additionally, `cbMan` is a callback which should accept up to two arguments representing part of the statblock which
 * require manual consideration/tagging, and an error message, respectively.
 * Where available, `cbErr` accepts the same arguments, and may be called when an error occurs (the parser encounters
 * something too far from acceptable to be solved with manual conversion; for instance, in the case of completely junk
 * data, or common errors which should be corrected prior to running the parser).
