Missing Values cause unexpected results

[BaddMann]

I've just finished watching your JNUC video and trying out the code.
I'm not running the remediation script until I've done a bunch of testing, but I'm finding that the Audit Compliance test is simply failing on a few of the tests as the plist doesn't exist or the key within the plist doesn't exist.

I was going to fork this and make the changes needed to account for missing files and keypairs, but then thought I'd better ask you first if this would be the right action or is this an intentional "thing".

Example log:

This is running on an El Capitan 10.11.6

Thanks for the help
