//
// ABSTRACT: This Fortran Module contains info on all the available
// GRIB2 Grid Definition Templates used in Section 3 (GDS).
// The information decribing each template is stored in the
// gridtemplate structure defined below.
//
// Each Template has three parts: The number of entries in the template
// (mapgridlen); A map of the template (mapgrid), which contains the
// number of octets in which to pack each of the template values; and
// a logical value (needext) that indicates whether the Template needs
// to be extended. In some cases the number of entries in a template
// can vary depending upon values specified in the "static" part of
// the template. ( See Template 3.120 as an example )
//
// NOTE: Array mapgrid contains the number of octets in which the
// corresponding template values will be stored. A negative value in
// mapgrid is used to indicate that the corresponding template entry can
// contain negative values. This information is used later when packing
// (or unpacking) the template data values. Negative data values in GRIB
// are stored with the left most bit set to one, and a negative number
// of octets value in mapgrid[] indicates that this possibility should
// be considered. The number of octets used to store the data value
// in this case would be the absolute value of the negative value in
// mapgrid[].
