VRFSearchAndBackup v0.0.5-alpha (2013-08-29)

## VRFSearchAndBackup v0.0.5-alpha (2013-08-29) ##
* Updated the backupVRF function so that the application will not log
into
any routers and retrieve results if the output file cannot be opened.
* Corrected 'mkdir' function to 'makedirs' so that directories will be
created recursively, if they do not exist.
* Added basic logging to file to track results if application has to
connect
to a router to run buildIndex().
* Suppressed error SPAM from stdout by adding stderr=(open(os.devnull,
'w'))
to the Queue() function. (Errors are still written to the log.)
