Comment (by jrobparsons):

 I think we need to verify the input arguments before the cs2cs.exe tool is
 called.

 I played with the '-e string' option, but the error messages generated by
 cs2cs are not suppressed. The documentation
 (https://trac.osgeo.org/proj/wiki/man_cs2cs) for the -e option talks about
 using the -b, -i, or -o options to return a value. These options appear to
 be invalid.
