Refactor picking to use one thread per entity

Added triangle visitor by refactor the triangle volume extractor
Added ability to do a ray intersection with a single volume without using a thread
Added entity collector
Use one thread for each entity
Ignore entities that don’t have a pick object
Removed list of triangle volumes stored on each entity
Use triangle visitor to test each triangle by creating a single volume on the stack
Added triangle and 3 vertex index to the pick event
