%> @brief "Super-object" encapsulating both a @ref as_fsel_grades and a @ref as_grades_data object

%> This class allows the input to be a dataset (@ref irdata) instead of a @ref log_grades
%>
%> @arg The @ref as_grades_data object calculates the grades vector, whereas ...
%> @arg the @ref as_fsel_grades performs itself the feature selection.
