Class Overview
Implementations of this interface are responsible for supplying the different executors used by different sections of the image pipeline.
A very basic implementation would supply a single thread pool for all four operations. It is
recommended that forLocalStorageRead() and forLocalStorageWrite() at least be
different, as their threads will be I/O-bound, rather than CPU-bound as the others are.
Implementations should return singleton objects from these methods.
