Detailed Description

Go4 TTree storage.

Storage instance using the central main go4 tree which is accessible as singleton. Each treestore instance adds at least one new branch to that tree and fills it with the data at the event pointer. Branch associated with this tree store may be written to the main tree file, or be located in another file which is specified by the filename parameter of ctor.
