Pack procedural growth ingredients

[meganrm]

Use Case

We want to include procedural growth ingredients using the new recipe schema. These ingredients start as a seed and grow based on pre-determined rules in a collision-avoiding manner. Possible options for growing subunits are cylinders (ref. issue #14) or spheres. It would also be great to include branching of ingredients based on biological parameters (e.g. actin).

Possible issues/subtasks

• Update the grow.py ingredient class to include parameters from the new recipe schema
• Create test recipe for grow ingredients
• Successfully pack grow ingredients with cylinder or sphere subunits
• Create interface with simularium viewer to visualize these ingredients
