Detailed Description

Class to store ADC counts during clustering.

This class defines the buffer where the pixel ADC are stored. The size is the number of rows and cols into a ROC and it is set in the PixelThresholdClusterizer

TO DO: the chip size should be obtained in some better way.

History: Modify the indexing to col*nrows + row. 9/01 d.k. Add setSize method to adjust array size. 3/02 d.k.
