Detailed Description

This class implements threshold algorithm to AlgoThreshold class. The algorithm defines a pulse in user-specified time window. A typical usage is to set the beginning of the window to be 0 (= start of the waveform) and integrate over the time of interest. By default, the ending is set to index=0, in which case it uses the ending index of the input waveform (i.e. full integration).
