Turning features on and off?

[Kingbadger3d]

Hi mate, started playing with some of your builds again but having issues. The code has changed a lot since i last was up to date with the code layout and features, Im trying to activate the denoise system (I also downloaded the wavelet version from your git) but when ever i add #define ENABLE_DENOISER i just get a load of error's?

Also you have many branch's on your git, adaptive sample, different denoise systems, opengl, etc etc. Could you add a text doc for each branch describing what the feature change is and how to activate it per branch.

For example how do I change from uni directional path tracer to bi directional, I cant see any obvious bool etc to switch from one to another.

Please could you just add a little note.txt for each branch in testing and whats needed and where it's needed within the code to turn on or expose the features.

Many thanks, James
