• Ability to have multiple fs modules on the same page. Now you can construct multiple independent fs modules.

var mainFsModule = BrowserFS.BFSRequire('fs');
var fsSecondary = new mainFsModule.FS();
fsSecondary.initialize(new BrowserFS.FileSystem.InMemory());
var fsTertiary = new mainFsModule.FS();
// etc.

• File descriptors are now numbers. Before, we gave applications File objects. Now, we give numbers.
