// Common style file for TkAl public plots
// --------------------------------------------------------------
//
// Defines a set of functions to define the plotting style and
// provide commonly used style objects such as histogram title
// and legends. Can be used in compiled code and uncompiled scripts.
//
// Always call TkAlStyle::set(PublicationStatus) in the beginning
// of your plotting script to adjust the gStyle options. Also,
// the behaviour of some other methods of this class depend on
// this, e.g. the histogram title displays "CMS preliminary" etc.
// depending on the PublicationStatus. Call TkAlStyle::set before
// declaring any histograms (or call TH1::UseCurrentStyle()) to
// make sure the style settings are used.
