<h4>New infrastructure for toy MC studies</h4>

A new class <tt>RooStudyManager</tt> has been added that is intended
to replace the present <tt>RooMCStudy</tt> framework for toy MC
studies on the time scale of ROOT release 5.26.
<p>
The present <tt>RooMCStudy</tt> is a small monolithic driver to
execute 'generate-and-fit' style MC studies for a given pdf.  It
provides some room for customization, through modules inheriting from
<tt>RooAbsMCStudyModule</t
