Detailed Description

A process to subtract the common channels noise from RawSignal type.

BASIC DOCUMENTATION : Full documentation to be added. A figure with the the pulses before and after applying the process.

This process tries to reduce the common noise of TRestRawSignals by two means :

Mode = 0: For each time bin, all time bins are gathered for all the signals and ranked increasingly. We take the middle bin and substract its values to all the bins corresponding to that time.
Mode = 1: The method is exactly the same but we take into account centerWidth% of the total number of bins center around the middle. The mean of these bins is used to do the correction.

Common noise identification in all signals or by blocks Written with TREX-DM architecture in mind (8 blocks with 68 signals each and gap of 4 ID between blocks)

Blocks = 0: All signals together.
Blocks = 1: 8 groups of signals, independent common noise reduction process for each group.

Output signal without base line subtraction.
