Matt K 6decf0b54b Remove pubsub and replace w/ polling head of chain (#122)
* Rename geth package structs to not be prefaced with package name

* No longer need to dump schema since Travis uses migrate

* Rearrange history package

* Removed double request for receipt from block rewards

* Remove Listener + Observers and Replace w/ Polling Head

* Potential Short term Issue w/ Infura (ignore these tests for now)
