// RootNameTag -- implementation of the root name tag parsing.
//
// This simple structure is used to parse a column name for a ntuple
// that can be of the form "[block_name::]column_name"
// The block name is an alpha numerical string whithout any white space.
// The column name is as defined by Root.
// isValid is set to false the name tag parsed was not correctly formed.
//
// The following method are defined in this file:
//	RootNameTag()
//      RootNameTag(const string& tag)
//      init(string tag)
// bool isValidBlockName(const string name)
// bool isValidColumnName(const string name)
