     Attributes in BioMart databases are grouped together in attribute
     groups and attribute groups can in their turn form a higher
     collection in an attribute category.  The attributeSummary
     function gives a summary of the attribute categories and groups
     present in the BioMart.  These group and category names can be
     used to display only a subset of the available attributes in the
     listAttributes function.

    mart: object of class Mart, containing connections to the BioMart
          database.  You have to create such an object using the
          function useMart and update this Mart object by selecting a
          dataset.
