class EventValueMap

  A filter destined to change the original value into another one according to a given map. Example:

  > filter = EventValueMap({1:”OPEN”, 2:”CHANGING”, 3:”CLOSED”})

  this will create a filter that changes the integer value of the event into a string. The event type is changed according to the python type in the map value.

  For now it only supports simple types: str, int, long, float, bool
