+mutation, and other data that fit into the ragged array schema for genomic
+location data.  The basic representation of such data provides a rectangular
+flat table interface to the user with range information in the rows and
+samples/specimen in the columns.  The @code{RaggedExperiment} class derives
+from a @code{GRangesList} representation and provides a semblance of a
+rectangular dataset.")
