Python3 API for QuickSmart Etherrain/8

The EtherRain/8 from QuickSmart is an Ethernet based irrigation controller with a custom web API. This is a simple Python3 API for talking to it.

Limitations

• The ER8 maintains its authentication state by IP address. So if another process or client on your system has authenticated with the ER8, then the login() function will succeed even with an invalid password.
• Due to the above limitation, a client with an invalid username/password on the same host can issue watering commands and retrieve state, etc.
• This API Assumes an Etherrain/8 and doesn't anticipate anything as regards the Etherrain/7P

class EtherRain:
    def __init__(self, addr, user, pw, timeout):

Class instantiation requires an IP address or hostname, username, and password with an optional timeout.
