Final Cut Pro grinds to a halt when using Metaburner on complex projects

[latenitefilms]

For example, I applied Metaburner to a nearly 2 hour timeline of BRAW clips (using BRAW Toolbox), and Metaburner takes a good 30sec to actually render a frame. I THINK this is because we're storing the entire FCPXML internally - and FCPX is taking a long time to read the FCPXML data (and probably processed data), each frame. Will have to investigate if we can do some caching or something.

@randomeizer - Any recommendations on good Swift profiling frameworks?

This should be fixed in next beta by using caching.
