Scantable Mathematics

It is possible to to simple mathematics directly on scantables from the command line using the +, -, *, / operators as well as their cousins +=, -= *=, /=. This works between a scantable and a float. (Note that it does not work for integers).

Currently mathematics between two scantables is not available

  ASAP>scan *= 1.05
  ASAP>sum = scan1+scan2
