/**
 * @file  RootUtils/InitHist.h
 * @author scott snyder
 * @date Oct 2007
 * @brief Initialize root's getline history.
 *        You'll need this if you use TTreeViewer using python
 *        as your interactive shell.  TTreeViewer pushes information
 *        onto the getline history list.  However, getline is initialized
 *        only when CINT is used as the shell.  If that isn't the case,
 *        then such attempts to push to the history will crash.
