Pre-Release TODOs

• move RangeProof code to back_maxwell.rs module
• double check documentation
• double check code
• don't use any yolocrypto features (i.e. stabilise decaf in curve25519-dalek)
• make a CONTRIBUTING.md

Future TODOs

• support other rangeproof schemes?
• make hash function choice configurable?
• make the code generic w.r.t. to a future Group trait
