`PhpGlobal` doesn't make much sense to me. `PhpGlobalFunctionsProxy` - does, IMHO.
Yeah, it's longer, but more obvious in it's intentions and more correlating with other code around.

And I don't think it's a wrapper. I think it's really more like a proxy class. It's passing calls through, not wrapping it.

So my proposal for class name is: `ETwigViewRendererPhpGlobalFunctionsProxy`
And for [comment](https://github.com/yiiext/twig-renderer/pull/13/files#L0R335): `Class-proxy for PHP-global functions`

What do you think?
