Pixel cluster -- collection of neighboring pixels above threshold.
Pixel cluster -- collection of pixels with ADC counts.
Class to contain and store all the topological information of pixel clusters: charge, global size, size and the barycenter in x and y local directions. It builds a vector of SiPixel (which is an inner class) and a container of channels.
