hb_input questionable output

[m4rc1e]

Users may not get the output they expect for each glyph. Here are some quick checks with Alegreya

>>> g.input_from_name('one.dnom')
(('aalt', 'frac'), '1')

dnom is desired

>>> g.input_from_name('aring.sc')
(('aalt',), 'Å')

smcp is desired

---

After skimming the code, I found HbInputGenerator uses memoization to find all the inputs for a given character.

>>> g.input_from_name('aring.sc')
[(('aalt',), 'Å'), (('aalt',), 'å'), (('c2sc',), 'Å'), (('smcp',), 'å')]

It will then use a min function to reduce it one input by minimising the found inputs.

>>> features, text = min(inputs) # inputs are in the previous code block.
(('aalt',), 'Å')

# aalt has been returned because:
>>> min(('aalt',), ('smcp',))
('aalt',)

I don't have an exact answer on how this should work but I should have a solution next quarter.
