Place compartments in scene as ingredients

[meganrm]

Use Case

For nesting compartments in new schema, we want to be able to pack them with the same collision detection as we do with ingredients.

Solution

We need to detangle the code.

Steps:

1. Create ingredients and create compartments (should a compartment be a attribute of an ingredient?)
2. create recipes
3. calculate volume of each compartment, and each compartment needs to know it's children
4. calculate the available volume of each compartment, ie env bounding box minus the volume of any children compartments
5. set counts for all objects
6. Build only environment grid
7. place any compartments that are children of the grid
8. build the children compartments
9. Iterate through nested compartments until all are placed
10. Pack non compartment ingredients
