/** 
 This plugin is designed to make root trees of low level data from the DAQ.
 Each low level data type will have its own tree in the file.
 Each event and each channel is a new entry in the tree.

 Trees will be named after the low level data type used to fill them.
 Currently the data types that are supported are: /n
   Df250WindowRawData /n
 The data types that will ultimately be supported are: /n
   Df125PulseIntegral /n
   Df125PulseTime /n
   Df125TriggerTime /n
   DF1TDCHit /n
   DF1TDCTriggerTime /n
   Df250PulseIntegral /n
   Df250PulseRawData /n
   Df250PulseTime /n
   Df250StreamingRawData /n
   Df250TriggerTime /n
   Df250WindowRawData /n
   Df250WindowSum /n
