BREAKING CHANGE: Migrated to `diagram-js@14` which removes touch interaction module, and dependency on unsupported `hammerjs` package. If you rely on touch interaction, you need to support touch interaction on your own.
deps: update to `diagram-js@14`
feat: allow to add to selection via lasso tool
Closes#2053
* 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).
