probe_value :
A probe for measuring the values of an xreal-typed signal at triggering events.

The probe_value primitive measures the value of an xreal-typed signal in at the specified triggering events and records the results in a table format to a text file named by the parameter filename.

The measurement can be triggered either internally or externally depending on the value of the parameter period. When period is greater than 0, the measurement is triggered internally at a period of period after an initial delay of delay. When period is 0, the change is triggered externally whenever the trig input changes to a different value.

The primitive can also measure and record the values of multiple inputs at once. In this case, the parameter num_in defines the number of inputs provided to in.
