Public: Generates a new Rempte instance.

api_host - HTTP host to send requests to, has to include schema (https or http) options - Hash with configuration options:

:token    - OAuth token to use (optional).
:username - Github user used for login (optional).
:password - Github password used for login (optional).
:origin   - Value of the origin request header (optional).
:headers  - HTTP headers to be send on every request (optional).
:adapter  - HTTP library to use for making requests (optional, default: :net_http)

It is highly recommended to set origin, but not to set headers. If you set the username, you should also set the password.
