Ranks

tblRanks contains ranks in the taxonomic hierarchy, shared across files. All programming should be done in a manner that does not cause problems if more levels are inserted into the hierarchy.

• RankID, integer 1 byte. Gaps between numbers allow insertion of new levels.
• RankName, text, 17 bytes maximum
• DefaultLevel, integer, 1 byte used to select a commonly used rank as the default when user is adding a new taxon
