Global Variables

The global namespace has a bunch of useful variables.

I don’t love these names but they’re not going to go anywhere, so you’re free to use them. In all likelihood in the future we’ll get together and create a bunch of nicer #define’s for them, so g_flTime will be accessible viaTime.Now, or just time etc.

`float`	`g_flTime`	Current time
