Move `sendMoney` func to `purchase` package

Create a new package for sending money. Take API keys as args which
obviously is not a good idea but it's a hackathon.

* Add functions in main.go to initiate hard-coded transactions for house
  buyer and seller
* Move from "com.teddywing" to "github.com/teddywing"
