I've made Part a concrete object, this is so it can be decomposed into multiple event lists, e.g. one for intro, one for chorus, etc.

Parts are expected to be played by one instrument or player e.g. a drum part might have multiple instruments, but often a part will have just one instrument e.g. a bass line.

I've removed skipping from Arpa, the combinator library for arpeggiator patterns. Allowing skipping meant there was an implementation leak in the API, plus I now feel skipping should be providence of beat patterns (via rests).

I've fixed a bug in building beat patterns - using foldr built them backwards so I've switch to foldl'.

Also I've added some more primitives empty, basic and aribtrary - next I need some proper combinators (not primitives).

I've added the module Majalan.Base.BeatPattern - this is the first draft of a combinator library for generating beat patterns.

I've added the first draft of Majalan.Base.Arpa - a combinator library to generate arpeggiator patterns.

Using it quickly announced that I need a similar library to make beat patterns.

I've implemented Chains and changed clickTrack to use a Chain.

Chains are potentially a very handy abstraction for building sequencers, arpeggiators and other automatic instruments.

I've improved the algorithm that builds an ImpulseMap from a Timeline. I've also removed the duplication of User context in the Advance object.

These improvements are a prelude to adding Chains - an abstraction Wumpus had for stepping through point sequences. Chains in Majalan will step through Impulse Maps.
