/**
 *The LEMuSRCryoHit class defines the Hit object for the Sample Plate. A hit is an elementary
 *component for the sensitive detection. As soon as particle enters in the specified 
 *volume, a hit object is created and will store any parameter the user wants to
 *consider.
 *The hit can then be plotted, printed or registered in a hit collection for further histogramming.
 *
 *However, it is not necessary to use hits objects since histograms can be filled
 *directly from the sensitive detector classes (cf. LEMuSRCryoSD.cc).
