Dustin Brody 81d5becc7b Switch hash functions, prevent underflow & verify that shuffling works (#149)
* prevent balance underflow, per spec implementation note

* verify that permutation shuffing works: add YAML dependency to be used for ingesting test cases; switch from blake2 to keccak256 to match EF test cases; remove inefficient naive-spec-version of shuffling algorithm now that protolambda's can be tested directly

spec updates (#34)
* spec updates

* make several constants uint64 to help minimize casting

* change comment style on fields and constants to make room for better
comments
* add BLSVerify and BLSAddPbkeys facades to insulate spec code from
milagro
* fix proof of possession type
