An evaluator evaluates and blends actions, producing the final matrices for all bones.

Initial empty evaluator API
e0954c0 
Move compiler to the same model as the evaluator API, make the
API take CaSkeleton values directly, and strict preconditions
for the structure of the CaSkeleton values.

Initial curve evaluator
d6745bc 
This is working towards skeleton evaluation. The
`CaEvaluatorSingleActionCurves` type separately evaluates the
translation, orientation, and scale, for a given bone in a skeleton
for a given action.

Add quadratic interpolation.

Introduce evaluated skeletons
9ac0f8c 
Introduce a new CaEvaluatedSkeletonMutableType that acts as storage
for evaluated joints. This allows for users to reason about space
usage within their programs: The skeleton types are the storage,
and evaluators act on that storage without performing significant
allocations themselves.

Add functions to produce deformation matrices.

Rewrite timeline handling
14b22bd 
This replaces the code in the single action evaluator with a general
class that calculates keyframes and progress values for interpolation.
This changes the semantics slightly: The final keyframe in an action
is _never_ reached; the action will loop back to the start on the frame
before the final keyframe. This may have consequences for keyframe
events, because an event on the final keyframe will never be evaluated.

Use spherical linear interpolation for quaternions
3861d71 
This fixes a bug caused by the use of standard linear interpolation:
Linear interpolation does not guarantee that it will use the
shortest path when interpolating a quaternion. This required using
the as-yet-unreleased jtensors 7.1.0 package.

Fix #23

A decision needs to be made as to what evaluators will be included in 0.1.0. Right now, only the most trivial evaluator is implemented: A single action evaluator. Presumably, evaluators could be composed rather than, for example, implementing another evaluator that processes multiple actions with blending and so on.
