WIP: added browserify bundle scripts to package.json

@tdurand WIP. Having trouble with this ... could you have a look?

The main.js contain the logic for parsing the command line and stuff, the core module is tracker.js

For some reason the main.js code fails to pass the browserify exporting, but as the code of the main.js isn't needed, I changed it to export the tracker.js only and it works

Then to use it you can import the script in dist/ and

movingThingsTracker.updateTrackedItemsWithNewFrame(detectionsOfThisFrame, frameNb);
// NB: We could simplify the API and auto increment frame by 1 when calling updateTrackedItemsWithNewFrame

const trackerDataForThisFrame = movingThingsTracker.getJSONOfTrackedItems();

Seems the uglify script isn't properly working yet, I let you have a look

close this as very old
