 * A viewer for BPMN 2.0 diagrams.

 * Have a look at {@link NavigatedViewer} or {@link Modeler} for bundles that include

 *
 *
 * ## Extending the Viewer
 *
 * In order to extend the viewer pass extension modules to bootstrap via the
 * `additionalModules` option. An extension module is an object that exposes
 * named services.
 *
 * The following example depicts the integration of a simple
 * logging component that integrates with interaction events:
 *
 *
 * ```javascript
 *
 * // logging component
 * function InteractionLogger(eventBus) {
 *   eventBus.on('element.hover', function(event) {
 *     console.log()
 *   })
 * }
 *
 * InteractionLogger.$inject = [ 'eventBus' ]; // minification save
 *
 * // extension module
 * var extensionModule = {
 *   __init__: [ 'interactionLogger' ],
 *   interactionLogger: [ 'type', InteractionLogger ]
 * };
 *
 * // extend the viewer
 * var bpmnViewer = new Viewer({ additionalModules: [ extensionModule ] });
 * bpmnViewer.importXML(...);
 * ```
 *
 * @param {Object} [options] configuration options to pass to the viewer
 * @param {DOMElement} [options.container] the container to render the viewer in, defaults to body.
 * @param {String|Number} [options.width] the width of the viewer
 * @param {String|Number} [options.height] the height of the viewer
 * @param {Object} [options.moddleExtensions] extension packages to provide
 * @param {Array<didi.Module>} [options.modules] a list of modules to override the default modules
 * @param {Array<didi.Module>} [options.additionalModules] a list of modules to use with the default modules

/**
 * A general purpose event bus.
 *
 * This component is used to communicate across a diagram instance.
 * Other parts of a diagram can use it to listen to and broadcast events.
 *
 *
 * ## Registering for Events
 *
 * The event bus provides the {@link EventBus#on} and {@link EventBus#once}
 * methods to register for events. {@link EventBus#off} can be used to
 * remove event registrations. Listeners receive an instance of {@link Event}
 * as the first argument. It allows them to hook into the event execution.
 *
 * ```javascript
 *
 * // listen for event
 * eventBus.on('foo', function(event) {
 *
 *   // access event type
 *   event.type; // 'foo'
 *
 *   // stop propagation to other listeners
 *   event.stopPropagation();
 *
 *   // prevent event default
 *   event.preventDefault();
 * });
 *
 * // listen for event with custom payload
 * eventBus.on('bar', function(event, payload) {
 *   console.log(payload);
 * });
 *
 * // listen for event returning value
 * eventBus.on('foobar', function(event) {
 *
 *   // stop event propagation + prevent default
 *   return false;
 *
 *   // stop event propagation + return custom result
 *   return {
 *     complex: 'listening result'
 *   };
 * });
 *
 *
 * // listen with custom priority (default=1000, higher is better)
 * eventBus.on('priorityfoo', 1500, function(event) {
 *   console.log('invoked first!');
 * });
 *
 *
 * // listen for event and pass the context (`this`)
 * eventBus.on('foobar', function(event) {
 *   this.foo();
 * }, this);
 * ```
 *
 *
 * ## Emitting Events
 *
 * Events can be emitted via the event bus using {@link EventBus#fire}.
 *
 * ```javascript
 *
 * // false indicates that the default action
 * // was prevented by listeners
 * if (eventBus.fire('foo') === false) {
 *   console.log('default has been prevented!');
 * };
 *
 *
 * // custom args + return value listener
 * eventBus.on('sum', function(event, a, b) {
 *   return a + b;
 * });
 *
 * // you can pass custom arguments + retrieve result values.
 * var sum = eventBus.fire('sum', 1, 2);
 * console.log(sum); // 3
 * ```

 * Methods that operate on and return arrays, collections, and functions can

 * value. Explicit chaining may be enabled using `_.chain`. The execution of
 * chained methods is lazy, that is, execution is deferred until `_#value`
 * is implicitly or explicitly called.
 *
 * Lazy evaluation allows several methods to support shortcut fusion. Shortcut
 * fusion is an optimization strategy which merge iteratee calls; this can help

 *
 * Chaining is supported in custom builds as long as the `_#value` method is

 *
