 /*! \brief %Study Interface

    The purpose of the %Study is to manage the data produced by various components of %SALOME platform.
   Most of the %Study operations are handled by the StudyManager and the StudyBuilder.
   What is left in the %Study interface are elementary inquiries.
   (Incidentally, we recall that a CORBA attribute is implemented as a pair of get
      and set methods.) A %Study is explored by a set of tools, mainly iterators
    , which are described further. Nevertheless, the %Study
     interface allows the search of an object by name or by ID.
     \note
     <BR><VAR>The Path </VAR>of an object in %SALOME application is much alike a standard path of a file.
    In general it's a string of names of directories divided by a slash '/'.
     <BR><VAR>The Context</VAR> is the current directory of an object.</P>
