* 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)
