v0.1.0

v0.1.0 of the Hedera Smart Contracts marks the initial form of reference Solidity Smart Contracts used by the Hedera network.

This initial version maps to v0.28 of the Hedera Services logic and introduces the IHederaTokenService.sol precompile that implements HIP 206.
Smart contract developers can utilize the interface to make HTS calls to create, transfer, mint, burn, associate and dissociate native tokens on the network.

Enhancements

• Npm artifact for v0.1 #95
• Add return value to fungible allowance #36
• Add Allowance/Approval methods to HTS precompile #29
• Default expiry modifier #4
• Update Solidity files for HIP-358 (token create through the precompile) #2
• Call update #1
