Logging and Module Rename

• A logging handler is now included - this cuts the boilerplate code you need to write in order to hook up the provider to your application. See the testWithLogging.py sample for how to use this.
• This release renames the module to raygun4py. You can now add it with from raygun4py import raygunprovider
• HTTP request data can now be added to the message if you are in a web environment.
