MetaHash API GO library

An unofficial Golang library for #MetaHash blockchain. This repository was folked from the reposity created by xboston and I contributed to the original repository. However, due to major changes I made, I decided to create a new repository to avoid introducing breaking changes to the original repository and affect systems that are already depending on the original repository.
