Using `self::` instead of `mooSignature::`?

[julienmru]

Dear all,

First of all, thanks for the great tool! It works really well :)

I had to override generateTemplate() but because of references to mooSignature:: in other functions I had to override updateSignatures() and functionProcessUsers() as well.

Could you consider using self:: instead of mooSignature:: in your static method calls?

Long story short: I had to do this to solve a use-case close to the one described in #4. Or maybe you can provide a way to use a custom callback function in generateTemplate() without overriding the class?

Best regards.
