To make the definition of supported digests more clear, we have refactored the

function calls.

Set represents a unique set of digests which allow for efficient lookup.
Dumping short codes is a function which takes in a digest set.
Any operation involving short codes may be considered secure if the list of digests added to the set is the complete list of referenceable digests.
Contains benchmarks for Add, Lookup, and Dump.
