/**
 * Invocation matcher which looks for sets of specific parameters in the invocations.
 *
 * Checks the parameters of the incoming invocations, the parameter list is
 * checked against the defined constraints in $parameters. If the constraint
 * is met it will return true in matches().
 *
 * It takes a list of match groups and and increases a call index after each invocation.
 * So the first invocation uses the first group of constraints, the second the next and so on.
