Added start of new pipeline detailed diagram.
Updated diagram
Started to refactor pipeline into tracker class to keep code manageable.
Pretty much starting from scratch other than a few basic kernels.
Forgot a few refactors
Beginning to refactor cuda code into separate files.
Added in debug rendering code.
Code looks much cleaner now.

Removed old triangulation code, stripped down old pipeline to bare bones.

Separated rendering debug pipeline from mesh tracking
Added regions and simplified pipeline at the expense of one more copy kernel when no filters are used.
More regions and reorganization.
