    # This API will create a "Results" folder on the IxNetwork Tcl Server
    # C: drive if it doesn't exist.
    
    # Important note:
    #     Users must verify if traffic started successfully.  If not, don't call 
    #     TakeSnapShot.  Or else you will get the previous stats left behind on the GUI.
    #
    #     If traffic started successfully and taking a snapshot failed, this API
    #     will return 0.
    #     If snapshot is ok, it will return the $$copyToLocalPathAndFileName.

    #    If using the HLT command to take snapshot:
    #        TakeSnapShot will put the csv result file to the path of your
    #        current destination.  For example:
    # 
    #        If you executed TaksSnapShot from /home/hgee, and you stated the destination
    #        as /home/hgee/results, then the csv snapshot result file will be in:
    #         /home/hgee/home/hgee/results/snapshot.csv.
    # 
    #    If using low level command to take snapshot:
    #         Then the csv snapshot result file will be in:
    #         /home/hgee/snapshot.csv.
    #

    #    Users could also select which statistics they want to collect.
    #    In the case of getting egress tracking stats, the GetEgressStats
    #    API creates a "EgressStats" statistic view.
    #    Users would need to call this API and pass in EgressStats.
