/* TYPES RELATED FUNCTIONS */

/* The basic idea of this function is to provide a mapping from possible entry types to
	possible things the user could enter. Then our code for the matching entry can simply
	use this mapping to determine if a given entry could be understood to match the user's
	input.

	There are two basic approaches we could take:
		Convert the user's entry into a list of types, see if the Entry type matches any of
			the conversions from this list. (the list comparisons will be MANY enums)
		Convert our Entry types to a list of acceptable string aliases. Then compare the
			user's input to this list. (the list will be a relatively small list of strings)

	My gut instinct is that the first case (comparison of a largish list of ints) will be
		faster, and so that's the one that's implemented here.

	The following are the minimum list of case-insensitive aliases that the user could enter:
	noun
	verb:
		ichidan
		godan
	adjective
	adverb
	particle

	Note that our File Parser will also expand to general cases, if not included already:
		For Example: v5aru -> v5aru,v5 (so that a search for "godan" will find it)
	Also note that the basic edict dictionary does not separate ikeiyoushi out from the
		category "adj", so further breakdown of the "adjective" type would be misleading
