Description

Filter module that is configurable for specifying common requirements for cross section signal definitions. This PR is a draft since other options may need to be added.

Features:

• Filter based on final state primary particles with optional KE thresholds
• Filter based on neutrino interaction properties: Nu flavor, In TPC, CC/NC, target PDG codes, modes
• Module checks a list of filters to accept events that pass one or more conditions (e.g., accept events containing particle A or particle B)

Some example signal definition configurations are added to fcls/signal_filters_sbnd.fcl.
