Pantheon RPC suport in Web3j library

Inspiration

RPC communication is not standardized among Ethereum clients. Because of that there needs to be a specific implementation of RPC communication in libraries.

What it does

It provides an interface in web3j library to access Pantheon specific RPC calls.

How we built it

We've forked the web3j github repository and implemented the interface.

Challenges we ran into

The most difficult part of the project was to get to know the structure of web3j library.

Accomplishments that we're proud of

It seems to work :)

What we learned

We've learned how important it is to standardize interfaces among clients and how to use Pantheon client and it's interesting Pantheon-specific features.
