GM_Projection_t.GetProjectionValues Method

Updated
GM_Projection_t .GetProjectionValues Method
Creates a new projection object using a comprehensive set of codes to define all coordinate system parameters. The only necessary parameter is the horizontal coord system code, all others are optional and will be supplied with defaults by GeoCalc. The parameters can also be used to specify a target projection and transformation to supply a way for users to define conversions between CRS's. The codes are assumed to be GC codes, but if none is found, GeoCalc will fall back to EPSG codes, and then BMG strings.
