/**
 * A modeler for DMN tables.
 *
 *
 * ## Extending the Modeler
 *
 * 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.$inject = [ 'eventBus' ]; // minification save
 *
 * // extension module
 * var extensionModule = {
 *   __init__: [ 'interactionLogger' ],
 *   interactionLogger: [ 'type', InteractionLogger ]
 * };
 *
 * // extend the viewer
 * var dmnModeler = new Modeler({ additionalModules: [ extensionModule ] });
 * dmnModeler.importXML(...);
 * ```
 *
 *
 * ## Customizing / Replacing Components
 *
 * You can replace individual table components by redefining them in override modules.
 * This works for all components, including those defined in the core.
 *
 * Pass in override modules via the `options.additionalModules` flag like this:
 *
 * ```javascript
 * function CustomContextPadProvider(contextPad) {
 *
 *   contextPad.registerProvider(this);
 *
 *   this.getContextPadEntries = function(element) {
 *     // no entries, effectively disable the context pad
 *     return {};
 *   };
 * }
 *
 * CustomContextPadProvider.$inject = [ 'contextPad' ];
 *
 * var overrideModule = {
 *   contextPadProvider: [ 'type', CustomContextPadProvider ]
 * };
 *
 * var dmnModeler = new Modeler({ additionalModules: [ overrideModule ]});
 * ```
 *
 * @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
