* use ES6 import / export
* UTILS: export individual utilities
* TESTS: localize TestHelper includes
BREAKING CHANGE:
* all utilities export independent functions
* library sources got ported to ES6. You must now use
a ES module bundler such as Browserify + babelify or
Webpack to consume this library (or parts of it).
* use bpmnFactory for cloning to ensure all relevant
elements have actual IDs
* don't copy dataAssociations, as they are visual elements
that will be created during element re-connection
NOTE: This fixes data input association not properly being
wired during target replace, too.
Closes#694, #693
This introduces a 'property.clone' event that allows
plugging into the cloning mechanism when cloning
nested extension elements.
