/** @class RootCnvSvc
 * @brief  Root Event Conversion Service which coordinates all of our converters.
 *
 * When a component requests an item not yet available on the TDS, 
 * the RootcnvSvc is called to find the appropriiate converter to gain
 * access to the data and put it on the TDS.
 * Based on SICb service written by Markus Frank.
 * If an item is mentioned in the jobOptions as one to be written out, it 
 * will be converted from TDS to ROOT by the appropriate converter
 *
 * Based on the RootCnvSvc of GLast.
