- * This is the sigma instances constructor. One instance of sigma represent
- * one graph. It is possible to represent this grapĥ with several renderers
- * at the same time. By default, the default renderer (WebGL + Canvas
- * polyfill) will be used as the only renderer, with the container specified
- * in the configuration.
- *
- * @param {?*} conf The configuration of the instance. There are a lot of
- * different recognized forms to instantiate sigma, check
- * example files, documentation in this file and unit
- * tests to know more.
- * @return {sigma} The fresh new sigma instance.
- *
- * Instanciating sigma:
- * ********************
- * If no parameter is given to the constructor, the instance will be created
- * without any renderer or camera. It will just instantiate the graph, and
- * other modules will have to be instantiated through the public methods,
- * like "addRenderer" etc:
- *
- * > s0 = new sigma();
- * > s0.addRenderer({
- * > type: 'canvas',
- * > container: 'my-container-id'
- * > });
- *
- * In most of the cases, sigma will simply be used with the default renderer.
- * Then, since the only required parameter is the DOM container, there are
- * some simpler way to call the constructor. The four following calls do the
- * exact same things:
- *
- * > s1 = new sigma('my-container-id');
- * > s2 = new sigma(document.getElementById('my-container-id'));
- * > s3 = new sigma({
- * > container: document.getElementById('my-container-id')
- * > });
- * > s4 = new sigma({
- * > renderers: [{
- * > container: document.getElementById('my-container-id')
- * > }]
- * > });
- *
- * Recognized parameters:
- * **********************
- * Here is the exhaustive list of every accepted parameters, when calling the
- * constructor with to top level configuration object (fourth case in the
- * previous examples):
- *
- * {?string} id The id of the instance. It will be generated
- * automatically if not specified.
- * {?array} renderers An array containing objects describing renderers.
- * {?object} graph An object containing an array of nodes and an array
- * of edges, to avoid having to add them by hand later.
- * {?object} settings An object containing instance specific settings that
- * will override the default ones defined in the object
- * sigma.settings.
