Some workflows will only work on certain operating systems or require certain
executables outside of Kepler (e.g. JNI based actors; R system, etc). It would
be useful to have an actor/parameters/attribute that could be configured by the
workflow author to check the OS and/or the existence of certain files
(executables?) that are needed by the workflow and then inform the user if
workflow will not run (i.e message like "This workflow will NOT run of the
current OS (Mac OS X)".
