/**
 * Use instead of `instanceof` as a more flexible type guard.
 * @param obj check if this object's CATEGORY matches the provided category.
 * @param category a string representing a category of VexFlow objects.
 * @param checkAncestors defaults to `true`, so we walk up the prototype chain to look for a matching `CATEGORY`.
 *        If `false`, we do not check the superclass or other ancestors.
 * @returns true if `obj` has a static `CATEGORY` property that matches `category`.
