OWD crashes if it cannot find .spd.xml files associated with nodes

[jgaeddert]

If the default_GPP_USRP_node is installed but the USRP device is not, OWD will crash because it cannot find USRP.spd.xml. OWD needs to either

1. ignore the node and throw a warning box, or
2. handle FileIO exceptions by 'crashing' gracefully

[jgaeddert]

You could use the python os module to check existence of the file first, viz

# ...
    if not os.path.exists(base_path + os.sep + filename):
        print "Warning! Could not find " + filename
        print "cannot import node " + nodename
        return False
#...

The suggested fix is more pseudocode than anything else. Someone needs to make a decision what the tool should do in such a situation and handle the error appropriately.
