Refactored LASC Connection
Refactored LASC Connection

Changed url encoding scheme to setting parameters required.  This
simplifies the url generation process significantly and makes the code
much more readable.

We also subclassed the get and post methods of requests and added
default timeout, and header provisions into them.

Continued improving and strengthening the comments

Renamed the JSON objects that were encoded with params to reflect their
new purpose.

Added a LASCLoginException class to catch/raise errors when signing in.

Method currently identifies wrong uersname/email and wrong password
errors.

Removed unnecessary headers, so only origin and user-agent are still
being used in our session.
