[Wien] Error in IRelast

[Laurence Marks]

I think some improvements are needed to IRelast from one of the developers:

a) Change and provide Peter with a better installation script. It seems
that there are numerous problems with this.

b) Go through the code/scripts and provide detailed user error & warnings.
These are not for the expert, rather they should be for a very novice who
understands little to no coding or Linux.

I know b) is a pain, but it is needed. I think IRelast must be close to the
top for user problems on the list!

As one example of good practice, the code could check for the existence of
an executable C_setupc1112 using, for instance, "which C_setupc1112" --
then give a readable error. (There is already a lot of this in the main
scripts.)
