//  Description:
//	Class PndEmcClusterLiloPos. Lilo is a combined linear/logarithmic digi 
//	weighting algorithm for	cluster position reconstruction. It features 
//	an energy dependent offset parameter and an effective addend 
//	counter. If more than one digi was found in the logarithmic sum for 
//	one angle, this sum is used for this angle. If not, the linear sum 
//	is used which normally includes more digis.
//
//	 Software developed for the BaBar Detector at the SLAC B-Factory.
// Adapted for the PANDA experiment at GSI
