- * ABSTRACT
- *
- * This component provides conversions between Geodetic coordinates
- * (latitude and longitude in radians) and Ney's (Modified Lambert
- * Conformal Conic) projection coordinates (easting and northing in meters).
- *
- * ERROR HANDLING
- *
- * This component checks parameters for valid values. If an invalid value
- * is found the error code is combined with the current error code using
- * the bitwise or. This combining allows multiple error codes to be
- * returned. The possible error codes are:
- *
- * NEYS_NO_ERROR : No errors occurred in function
- * NEYS_LAT_ERROR : Latitude outside of valid range
- * (-90 to 90 degrees)
- * NEYS_LON_ERROR : Longitude outside of valid range
- * (-180 to 360 degrees)
- * NEYS_EASTING_ERROR : Easting outside of valid range
- * (depends on ellipsoid and projection
- * parameters)
- * NEYS_NORTHING_ERROR : Northing outside of valid range
- * (depends on ellipsoid and projection
- * parameters)
- * NEYS_FIRST_STDP_ERROR : First standard parallel outside of valid
- * range (
