import PySpin does not work

[alifuaziz]

When trying to import PySpin, Ryan was unable to do so for one of the computer that he was using. (But did work for another computer he setup). Everytime he pulls updates, he might have to re-fix the issue.

Now, he will have to either fix the underlying reason or we could using the following snippet at the top of the spinnaker.py module.

try: 
    import PySpin
except ImportError:  
    import pyspin as PySpin

instead of simply import PySpin.
