Basic Nest filter for input variables. This class is meant to provide Nest with input coming from the web requests.
Class BasicFilter
An instance of this class must be set as the Nest.filter property; Nest will call the filter method of the instance at proper time, and store its return value into Nest.inputVars.
This base class just provides nest with the sum of Request.gets and Request.post dictionaries, effectively feeding all the standard input fields into Nest.inputVars.
