Noted a few "todo" problems arising from some trunk features being unaccounted for

Trying to finish off graph building code for core rigidbody sim objects

Code cleanup - only perform pose graph operations build if there are bone ops to handle

Add operation for initialising object's transform stack

Fleshing out creation of operation nodes for pose eval

Basic relationships between pose-component nodes

Comments

Start of pose-component graph validation

First pass at determining whether a bone is a credible source-node

Add some more missing component fetching code

Added todo notes for resolving problems with node creation/referencing

Added notes about additional checks we could perform for sources and sinks

Create and cleanup finding of "sources and sinks"

Get rid of sources/sinks rubbish for pose graph validation

That approach was far too hard to get right (even though it would be promising
to reduce the number of operations we need to perform)

Added basic SCons build script

This is adapted from the relevant build script for the modifiers module

Added WIP notes to update flushing to ensure that tagged-count gets updated

Fix for unterminated line

Ported over handling for boids

For now, each particle system will simply be represented as a blackbox operation step

First attempt to partially port some of the particle graph-building code
