Optical Processes

[hhollenb]

NB: This code isn't meant to be integrated yet, but rather serve as a reference point and discussion forum for how optical are going to be implemented.

Overview of contents

• OpticalModel: this is the base class for optical physics
• OpticalProcess: this is the base class for optical processes. Optical models are uniquely identified with optical processes, so the OpticalProcessImpl template is a helper to define processes from static methods in optical models.
• ImportOpticalProcess: like ImportProcess but only has lambda physics tables for imported data
• ImportOpticalProcesses: builds and stores ImportOpticalProcesses from raw ImportData
• ImportedOpticalProcessAdapter: adapter class used by OpticalProcess to create step limiter grids.
• OpticalPhysics.hh: contains structs of data, indices, and grids used by optical processes
• OpticalPhysicsParams: register optical model actions in the action registry and builds grid data in OpticalPhysics.hh on both host and device.
• GenericGridInserter: helper class to build and insert grids into a collection on host
• AbsorptionModel: A sample optical model using this framework

Todo

• Finish adding documentation and cleaning up code
• Ensures it builds
• Add some kind of OpticalProcessBuilder
• Add tests that imported data is built correctly
• Make sure imported optical process macro xs tables are indeed cross sections and not mean free paths / attenuation lengths / etc.
• Add remaining optical processes
• Change execute to use OpticalCoreData etc.
• Connect executors and interactors to Soon's implementations
• Add discrete optical action to select optical actions
• Separate code into subfolders?
• Split up ImportProcessClass?
