2019-10-31	Call symbolic generator inside code templates	Adrian Kummerlaender
	This paves the way for dropping in other LBM collision models. As a side benefit the default momenta calulcation is now fully inlined where possible.

	It's time to extract the generator-part of my GPU LBM playground and turn it into a nice reusable library. The goal is to produce a framework that can be used to generate collision and streaming programs from symbolic descriptions. i.e. it should be possible to select a LB model, the desired boundary conditions as well as a data structure / streaming model and use this information to automatically generate matching OpenCL / CUDA / C++ programs.
