ValueError: structures must have the same size

[RoyThomsonMonash]

This problem happens when there is a mismatch in the version of an existing Loop project file with the version of the module current being used. Even when a mismatch occurs this exception only happens when an underlying structure has changed.

I am adding a check for version mismatching which will inform the user and abort.
I will also add an optional overwrite parameter that will overwrite the file if the version is different.
