Function getParamUnion

commands/util.go:430–449

getParamUnion(keyValArrAnnots, keyValArrParams, key) returns the union of parameters listed under annotations (keyValArrAnnots, using key) and bound parameters (keyValArrParams). Bound parameters will be denoted with a prefixed "*", and finalized bound parameters (can't be changed by user) will be d
