Detailed Description

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.
