/*
 * POPULATE_METADATA_STRUCT
 *
 * This routine just queries the GDAL raster file for all the metadata
 * that can be squeezed out of it.
 *
 * The resulting matlab structure is by necessity nested.  Each raster
 * file can have several bands, e.g. PNG files usually have 3, a red, a
 * blue, and a green channel.  Each band can have several overviews (tiffs
 * come to mind here).
 *
 * Fields:
 *    ProjectionRef:  a string describing the projection.  Not parsed.
 *    GeoTransform:
 *        a 6-tuple.  Entries are as follows.
 *            [0] --> top left x
 *            [1] --> w-e pixel resolution
 *            [2] --> rotation, 0 if image is "north up"
 *            [3] --> top left y
 *            [4] --> rotation, 0 if image is "north up"
 *            [5] --> n-s pixel resolution
 *
 *    DriverShortName:  describes the driver used to query *this* raster file
 *    DriverLongName:  describes the driver used to query *this* raster file
 *    RasterXSize, RasterYSize:
 *        These are the primary dimensions of the raster.  See "Overview", though.
 *    RasterCount:
 *        Number of raster bands present in the file.
 *    Driver:
 *        This itself is a structure array.  Each element describes a driver
 *        that the locally compiled GDAL library has available.  So you recompile
 *        GDAL with new format support, this structure will change.
 *
 *        Fields:
 *            DriverShortName, DriverLongName:
 *                Same as fields in top level structure with same name.
 *
 *    Band:
 *        Also a structure array.  One element for each raster band present in
 *        the GDAL file.  See "RasterCount".
 *
 *        Fields:
 *            XSize, YSize:
 *                Dimensions of the current raster band.
 *            Overview:
 *                A structure array, one element for each overview present.  If
 *                empty, then there are no overviews.
 *            NoDataValue:
 *                When passed back to MATLAB, one can set pixels with this value to NaN.
 *            ColorMap:
 *                A Mx3 double array with the colormap, or empty if it does not exists
