console.trace/time/timeline updates

[paulirish]

Followup from #93 and #13…

• lets show an example from remysharp on how we can pass args to console.trace effectively
• calling console.timeline() a few time works fine, it just concatenates onto a longer recording in the devtools.

I asked remy about console.trace and he asked if it is about the crbug he opened a couple months back. Not sure what example you were referring to exactly for that.

and also with the new UI of the timeline panel, i'm unclear about how the console.timeline nesting works. I dont see it working the way I thought it did

Another, console.time()s new behavior in timeline flame chart mode.
