//******************************************************************************
// Filename : JetSplitMergeTool
// Author : Ambreesh Gupta
// Created : November, 2001
//
// DESCRIPTION:
//
// Cone algorithms generally produce overlapping jets. These jets are then
// passed through a Split Merge algorithm to create seperated jets. This
// is an implementation of one such algorithm.
//
// The steps of the algorithm are:
// - <to be written>
//
// PROPERTIES (JobOption Parameters):
//
// ProtoJetContainerLoc string "Default" Key for ProtoJet input.
// JetContainerLoc string "Default" Key for Jet list to output.
// OverlapFraction double 0.5
//
// HISTORY
// 05Nov01 agupta. First version
// 15Aug02 agupta. Fix phi-wrapping.
