// BEGIN_HTML
// Template class RooCacheManager manages the storage of any type of data indexed on
// the choice of normalization and optionally the set of integrated observables.
// The purpose of this class is to faciliate storage of intermediate results
// in operator p.d.f.s whose value and inner working are often highly dependent
// on the user provided choice of normalization in getVal(). 
//
// For efficiency reasons these normalization set pointer are
// derefenced as little as possible. This class contains a lookup
// table for RooArgSet pointer pairs -> normalization lists.  Distinct
// pointer pairs that represent the same normalization/projection are
// recognized and will all point to the same normalization list. Lists
// for up to 'maxSize' different normalization/ projection
// configurations can be cached.  
// END_HTML
