Ability for a client to make payments

[justin1121]

Once a worker has completed a job the client who issued the job needs a way of compensating the worker. The simplest flow for this is that once the trained model has been received the client sends a certain amount of ether to the worker via an ethereum network.

Prerequisites

There are some ethereum blockchain identity issues that must be solved along with this:

Private key generation: #8
Default wallet to use: #6
Encrypted Wallet: #5
