Subject: [PATCH] From David Guthrie, " In the constructor in removes any
 options beginning with "-psn" from argv on OSX by calling the "remove"
 method.  When a .app run is created in OSX, which is required to get a fully
 functioning UI application, the OSX finder passes a -psn_XXXX option to the
 application where the XXXX refers to a unique process number.  An example
 option would be "- psn_0_37617665".  The argument parser was choking on this
 option in all the osg example applications."
