A few minor changes:

  - In writefits.c, CRVAL for the Stokes axis has now (the correct value of) 1 rather than 0.

  - In writefits.c, CDELT values are written as floats rather than doubles. This is to stop the CASA viewer complaining.

  - In task_limesolver.py and task_raytrace.py, moldatfile is now expected to be a scalar not a list.

  - In task_limesolver.py, the user now has the choice to specify scalar values if they want to (instead of single-element lists) for functions ('scalarConst' or 'vectorConstR') which take only one parameter.
