MAKEMAP default method

When running MAKEMAP, you indicate the method it is to use by setting the METHOD parameter on the command line. In the past, if you failed to do this you would be prompted for a value for METHOD, with the suggested default of "REBIN". I've changed this so that METHOD will now default to "ITERATE" and you will no longer be prompted if it is not specified on the command line.

So note, if for any reason you want to use the "REBIN" method, you will now need to indicate this by adding "METHOD=REBIN" to the command line.
