fuse

fuse is the next generation XENONnT simulation software. The goal of this project is to unify epix and WFSim into a single program. fuse is based on the strax framework, so that the simulation steps are encoded in plugins with defined inputs and outputs. This allows for a flexible and modular simulation chain.
