------------------------------------------------------------Why Make This?
Because sometimes there is the need to create an Ethereum Transaction without running a node such as from an app running on a mobile device.
It is also useful for deploying contracts for development purposes, if you simply find truffle to be more trouble than it is useful, or would prefer address consistency.

Disclaimer
This project as it stands exposes the private key of the sending address. Do not use this for production but only for learning purposes and to gain a better understanding of how contracts are deployed on Ethereum.
This project also has the potential to pollute the network which we would all do well to avoid as much as possible. The current contracts deployed using send-tx.js include a public function for self-destruct (callable by anyone; Yes, another major security flaw if this was used in production). If you remember the days (or even if you don't) when your VHS tape had a sticker that said "Be Kind, Please Rewind" then adhere to the new "Be Kind, Please Self-Destruct your Contract".
