This initial release of the Computable protocol provides an implementation of Token Curated Registries (TCRs). These contracts are similar to those in https://github.com/skmgoldin/tcr, but with some potential security issues addressed. Notably, systematic use of SafeMath has been added #61, and the Open Zeppelin ERC20 contract is used in place of EIP20 contracts #56.
Future releases of the Computable protocol will add additional features, working towards a full fledged tokenized data structure implementation to construct a tokenized data market (https://arxiv.org/abs/1806.00139)
