Sort and transpose the UV data set. The command has two different behaviours, depending on the /FILE option.
Without /FILE, the command works on the current UV data, loaded by command READ UV File, and creates a transposed, ordered copy of the UV data. The Key can be TIME for Time-Baseline ordering, BASE for Baseline-Time ordering. The sorted UV data is then available in variable UVS for further plotting. This is only done in an internal buffer. WRITE UV will **NOT** write this sorted, transposed, buffer.
With the /FILE option, the command creates in FileOut a sorted (but not transposed) copy of the UV data file specified in FileIn.
