 *
 * The library makes a distinction between input and output parameters
 *  due to the dynamic behaviour of the Cytoscape library.
 *
 * For a input parameter it will always expect:
 *  - Cy.Collection
 *      The input can be any element (node and edge) collection.
 *  - Cy.NodeCollection
 *      The input must be a node collection.
 *  - Cy.EdgeCollection
 *      The input must be a edge collection.
 *  - Cy.Singular
 *      The input must be a single element.
 *  - Cy.NodeSingular
 *      The input must be a single node.
 *  - Cy.EdgeSingular
 *      The input must be a single edge.
 *
 * For a output of a function it will always give:
 *  - Cy.Elements
 *      The output is a collection of node and edge elements OR single element.
 *  - Cy.EdgeCollection
 *      The output is a collection of edge elements OR single edge.
 *  - Cy.NodeCollection
 *      The output is a collection of node elements OR single node.
 *
 * A number of interfaces contain nothing as they serve to collect interfaces.

     * Layouts
     * http://js.cytoscape.org/#layouts
     *
     * The function of a layout is to set the positions on the nodes in the graph.
     * Layouts are extensions of Cytoscape.js such that it is possible for
     * anyone to write a layout without modifying the library itself.
     * Several layouts are included with Cytoscape.js by default,
     * and their options are described in the sections that follow
     * with the default values specified.
     * Note that you must set options.name to the name of the
     * layout to specify which one you want to run.
     * Each layout has its own algorithm for setting the position for each node.
     * This algorithm influences the overall shape of the graph and the lengths of the edges.
     * A layout’s algorithm can be customised by setting its options.
     * Therefore, edge lengths can be controlled by setting the layout options appropriately.
     * For force-directed (physics) layouts,
     * there is generally an option to set a weight to each edge
     * to affect the relative edge lengths.
     * Edge length can also be affected by options like spacing
     * factors, angles, and overlap avoidance.
     * Setting edge length depends on the particular layout,
     * and some layouts will allow for more precise edge lengths than others.
