6  * Description: JetBranches holds branches created from a jet collection
7  * created by Satoru Jet Finder processor.
8  * JetBranches has two steerable parameters which are optionally
9  * set in the steering file:
10  * - writeExtraParameters: if set to TRUE, the fill function
11  * calculates some extra parameters using parameters provided
12  * by the jet finding algorithm. Default value is FALSE.
13  * See class data members for a list of extra parameters.
14  * - writeTaggingParameters: if set to TRUE, the fill function
15  * creates branches for jet parameters coming form flavor tagging
16  * processor. If no flavor tagging processr is used, this should
17  * be set to FALSE to prevent errors. Default value is FALSE.
18  * See class data members for a list of extra parameters.
