/**
Generic change-detection helper used to help build / artifact generation /
etc. steps detect whether or not they need to run. Returns a function whose
input is a Set of input files, and subsequently executes the action function
(which does the actual work: compiles, generates resources, etc.), returning
a Set of output files that it generated.
The input file and resulting output file state is cached in
cacheBaseDirectory. On each invocation, the state of the input and output
files from the previous run is compared against the cache, as is the set of
input files. If a change in file state / input files set is detected, the
action function is re-executed.
@param cacheBaseDirectory The folder in which to store
@param inStyle The strategy by which to detect state change in the input files from the previous run
@param outStyle The strategy by which to detect state change in the output files from the previous run
