Reimplement TempoInventory around TypedOrderedDict instead of TypedList #402

Closed trevorbaca closed 7 years ago

trevorbaca commented 10 years ago

This will make it possible to say ...

tempo_inventory['allegretto']

... instead of (or in addition to) ...

tempo_inventory[2]

... which will increase the readability of segment definition.py modules.

Same probably applies to ClefInventory, TimeSignatureInventory, InstrumentInventory, PerformerInventory, MarkupInventory, OctaveTranspositionMappingInventory and PitchRangeInventory.

Do after current scores.

Renamed TempoInventory to TempoList in 2.20 precisely for this reason.

Closing this issue.

If we want a true TempoInventory (with dictionary-like interface) in future then we can implement in future. And probably best to call TempoDictionary.
