Fractional	Transformation implementing BasicList._FRACTIONAL.
LikeA	Transformation implementing C4List.LIKE_A.
PartsVisitor<T>	Helper for transformations which treat separate parts of a call, like Fractional, Finish, and LikeA.
RemoveIn	Push Ins down a call tree and adjust Prim timing where possible.
TransformVisitor<T>	TransformVisitor is a superclass to eliminate common code when writing tree transformations.
ValueVisitor<RESULT,CLOSURE>	ValueVisitor is a superclass to eliminate common code when writing tree transformations.

Package net.cscott.sdr.calls.transform Description

This package contains code to parse call lists and transform call abstract syntax in various ways.

Tests:

Square thru is "2 beats per hand", so square thru 1 1/2 takes 3 beats. Tests call evaluation, in removal, and fractionalization.
