Limits the frequency of messages to nMsg which is given per minute.

If the limiter detects more messages, it traces randomly selected messages with the given frequency on the vtracer until the frequency falls under the threshold long enough.(see below)

Before this the ltracer gets a StartLimiting message. In-between you receive ContinueLimiting messages on the ltracer every reminderPeriod seconds, with the number of suppressed messages. Finally it sends a StopLimiting message on the ltracer and traces all messages on the vtracer again.

A budget is used to decide when to start limiting and stop limiting, so that the limiter does not get activated if few messages are send in high frequency, and doesn't get deactivated if their are only few messages which come with low frequency. When messages arrive in shorter frequency then by the given thresholdFrequency budget is earned, and if they arrive in a longer period budget is spend. If budget is gets higher then budgetLimit, the limiter starts, and if it falls below minus budgetLimit the limiter stops.
