-- Given an interval vector for a mos, produce the name for that interval.

-- Prefix lookup is done automatically if no prefix is provided; defaults to

-- "mos" if no prefix is found. Prefixes are used for the full name for an

-- interval, whereas abbrevs are used for the abbreviated form. (This is

-- because some abbrevs are shorter than the corresponding prefix.)

-- Formats are as follows:

-- - NONE: full name, eg "perfect 4-diastep"

-- - SENTENCE-CASE: same as NONE, but with capitalized first letter

-- - SHORTENED: shortened form, eg "Perf. 4-diastep"

-- - ABBREV: abbreviated form, eg "P4dias"
