/*  Selecting Cells from a Container of CaloCells
                                        H. Ma  Sept 2000
    The constructor takes a pointer to  ObjectVector<CaloCell>
    Two selection implemented:
       delta_eta, delta_phi around a fix eta,phi, and
       a cone of size dR around a fixed eta,phi
    An optional sampling layer requirement.
    Using the templated method, Tselect, user can write a
    function object with the operator()(CaloCell*) to select
    the wanted cells.
    Each select call clears previous selection.
    methods et() and energy() return et and energy.
    list of cells can also be accessed through iterators.
 
   Mod 17 Jun 2004 David Rousseau: work off big CaloCellContainer
 
   Mod 21 Sep 2004 Damir Lelas: -speeding up using "CaloDetDescr/CaloDetDescrManager" class.
                                -vector of cells added to an exsisting list of cells
 
   Mod 11 Oct 2004 Damir Lelas: -new method "select_nstrips" added; possibility to get number
                                 of strips around given (eta,phi) direction for
                                 (ncell_eta,ncell_phi) specified. The List of cells replaced
                                 by the Vector of cells.
