Third release 0.3.1 beta 2

Includes the updated C files

Third release 0.3.1 beta 1

• Added the C version. This includes a sample application but is meant to be
  the basis for other software in need of a way to communicate with a Presto
  server. Note that the license for the C version is GPLv3 to be in line with
  other software that I intend to use this with.
• Update to Python version: Made it a bit quicker by lowering the time
  between requests to the Presto server when data is being received.
  Added the runquery function.
• Added the Presto data types added in V0.66 (date/time/timestamp) to
  C and Python.

Second release 0.2.0 beta 1

Python version:

• Client properly detects when a request is finished. The instance of the client may then be re-used for a new query
• Updated the presto client protocol. Client no longer uses the 'state' variable, only the presence of a 'nextUri' link. If server responds with http code 503, the request will be retried.
• Some changes in naming of methods
• Added the error message from the database if the query failed
• Improved error handling
• Updated documentation

Initial release 0.1.0 beta 1

Initial release of PrestoClient, a Python class to communicate with a Presto server. Presto is a fast query engine developed by Facebook that runs distributed queries against Hadoop HDFS servers.
