 JetResponseToolsConfig: A helper module for configuring jet moment
 tools, in support of JetRecConfig.JetModConfig.

IMPORTANT : all the getXYZTool(jetdef, modspec) functions are meant to be used as callback from the main JetRecConfig module 
when we need to convert definitions of tools into the actual tools. At this point the functions are invoked as 
 func(jetdef, modspec)
Hence they have jetdef and modspec arguments even if not needed in every case.
