Detailed Description

template<class rCore> class rTreeBase

A template class with IOfileVI interface to use a ROOT-Tree.

rTreeBase has all the IOfileVI operations defined (open, close, readEvent, writeEvent, etc).
rTreeBase class needs the main branch class of the ROOT tree as a template argument. The name of the class is also needed by ROOT. The template and its name are forced arguments of the constructor!.

The Tree should have only one main branch, the main branch is defined using the template "rCore".
The operations of open() and close() are overwriten from rTFileBase, in order to set the address of the main branch of the tree to the template class rCore.
It provides the method to read(), write() from/to a ROOT-tree.
the IOfileVI interface cames from rTFileBase.
