Parent theme should check if Tersus functions exist

[Avengio]

In order to be able to add or change Tersus functions from within the child theme, the parent theme should check to see if the function has been declared from the child theme.

Ooh, good one.

Also, hi!

Just updated the issue description a little bit.

One a related note, would it be useful to namespace all Tersus-specific functions with a tersus- prefix?

I like the idea of a prefix. -b

Prefix would be good. Fairly common practice if I recall.

Good enough. We’re already prefixing our custom title, comment callback, and gallery functions … may as well do the whole works while we’re wrapping everything with stylish function_exists shiz.

I’ll be implementing the wrappers shortly.

All theme functions have been properly namespaced per commit 2cc1d220ae5aeb7cbc73acd06ea36716f7e402df

Let me know if you spot anything funky.
