"""
Resolve differences between two parts (here a score template and analysis part) with
one defined as the reference part (score) and the other to be adjusted (analysis).
Changes made:
1. Number of measures.
Often analyses have fewer measures than scores as the last chord is reached
before the last measure, and those 'empty' measures are not explicitly encoded.
This function adds empty measures to the analysis, padding it out so that they match up.
2. Last measure duration.
In the case of a part with an anacrusis, the first measures and last measure are incomplete:
their combined value is equal to one full measure.
Romantext supports the encoding of an anacrustic initial measure (e.g. m0 b3) but there
is no equivalent way of setting the final measure's duration.
This function shortens the final measure's duration to match that of the score
in the case of a part with anacrusis (no action otherwise).
3. Remove duplicated (redundant) time signatures.
Where analyses have repeat measures, and where those measures have a time signature,
the time signature is repeated leading to duplicates that are redundant.
This is especially common when repeating the first measure.
This function removes those redundant time signatures.
TODO: promote this up to Roman text itself.
:param referencePart: the 'model' part, defining the 'correct' values.
:param partToAdjust: the part to alter according to values in the referencePart.
