#5 JobLauncher Feature Request: Set input extension type for inputFile

[Scott Forest Hull II]

With the new ability of NiCE to use multiple input files by calling the addInputType and the way the operation can handle file extensions, I was wondering if we could add a setter operation on the JobLauncher to set the FIRST input file's extension format as well. This will help cut down on local project workspace "junk" and help the developer demonstrate to the user which input files are appropriate for launching.
