This interceptor logs the amount of time in milliseconds. In order for this interceptor to work properly, the logging framework must be set to at least the INFO level. This interceptor relies on the Commons Logging API to report its execution-time value. TODO: Describe the paramters for this Interceptor. TODO: Discuss some possible extension of the Interceptor.
