Custom slim builds

[jonaslund]

I'm pressed for performance space, and would like to have the option of building a custom version of Tone.js that only includes a subset of features, let's say, I only need to use the Tone.Synth, no AM/FM Synths etc, and only the Sequencer.

How could I reduce the total kb's of usage from Tone.js by building a custom limited slimmed down version?

Thank you for a super library :)
