R interface to bitcoin daemon

Creates R6 class which allows to interact with official bitcoin daemon using json RPC methods.
Using sapply or lapply you can easily manage a farm of bitcoin nodes and mockup a complete environment.
Be aware each node requires own copy of blockchain unless you are using regtest mode which runs private empty blokchain.
If you want to run multiple nodes of testnet or mainnet you should start single instance, fully synchronize it and copy blockchain data to rest of your nodes.
Names of methods match to names listed in official developer reference. Not all methods are implemented, for those which aren't you can use x$rpc(method, params) method which allows any other json-rpc method.
There are also many helper methods, some of them uses system calls and may not work on non-linux OS.

Usage

Example usage on localhost.

library(rbitcoind)
btcd = bitcoind$new(rpcuser = "username", 
                    rpcpassword = "password", 
                    regtest = TRUE)
# run daemon on localhost
btcd$run()
# print daemon summary
print(btcd)
# daemon summary as data.frame
btcd$status()

# instantly mine 5 blocks (in regtest mode only and v0.11+)
btcd$generate(5L)
# various info about node and network
btcd$getinfo()
# current state of your blockchain
btcd$getblockchaininfo()

# stop daemon instance
btcd$stop()

The CI process run tests which includes setting up new private blockchain using regtest mode and populating blocks. You can find the process in .travis.yml file and tests/tests.R.
