/** \class CSCHitFromStripOnly (old comment below)
 *
 * Search for strip with ADC output exceeding theThresholdForAPeak.  For each of these strips,
 * build a cluster of strip of size theClusterSize (typically 5 strips).  Finally, make
 * a Strip Hit out of these clusters by finding the center-of-mass position of the hit
 * The DetId, strip hit position, and peaking time are stored in a CSCStripHit collection.
 *
 * Be careful with the ME_1/a chambers: the 48 strips are ganged into 16 channels,
 * Each channel contains signals from three strips, each separated by 16 strips from the next.
