-- Function that encodes a sequence of mossteps into a vector.
-- Step sequences of L's and s's are encoded into a vector containing how many
-- L's and s's there are. Steps that denote alterations by a chroma are allowed
-- since they can be expressed as the sum (or difference) between multiple large
-- and small steps:
-- - c: a single chroma; the difference between a large and small step, or L - s
-- - A: an augmented step; a large step plus a chroma, or 2L + s
-- - d: a diminished step, a small step minus a chroma, or -L + 2s
-- Proposed encoding (work-in-progress):
-- 2 = Large size plus 2 chromas, or 2x-aug size for period intervals
-- 1 = Large size plus 1 chroma, or augmented size for period intervals
-- 0 = Large size, or perfect size for period intervals
-- -1 = Small size, or diminished size for period intervals
-- -2 = Small size minus 1 chroma, or 2x-dim for period intervals
-- Encoding can continue for any number of chromas; only [-2, 2] is shown for
-- demonstration.
-- Large/small size is translated to major/minor, or aug/perf/dim based on what
-- interval it is (nonperfectable vs dark gen vs bright gen).
-- Encoding can be adapted for use with mos notation (EG, diamond-mos), where
-- the values denote how many chromas are added/subtracted.
