// MODULE WindBarbs
// CATEGORY RAMS
// DESCRIPTION Creates Wind Barbs from a 2d vector field
// INPUT data; value list or field or string or string list; (none); wind vector data, assumed to be in knots
// INPUT barbs; group or field or series or value list or string list; (none); the wind barbs file.  Contains a group of fields describing the barbs.
// INPUT scale[visible:0]; scalar; (input dependent); scale factor for size of barbs
// OUTPUT wind_barbs; group; wind barbs for each category of wind vectors
// End MDF
//
// comment: This macro chooses a glyph from an imported set of glyphs based on the data value.  Thus it is similar to "annotation glyphs" (see the AutoGlyph man page), but for this application, annotation glyphs were not appropriate since the glyphs are for vector data, and are also required to change direction based on the direction of the vector data.  Annotation glyphs are for scalar (categorical) data and are simply placed at the location of the data value in space. 
// comment: 
// comment: This macro loops over each category, choosing the appropriate glyph based on the magnitude of the data.   A glyph is created and appended to a group of glyphs.
