/**
 * Finds all [connected components][] in a graph and returns an array of these
 * components. Each component is itself an array that contains the ids of nodes
 * in the component.

 * [connected components]: http://en.wikipedia.org/wiki/Connected_component_(graph_theory)

 * @example

 *
 * ```js
 * graphlib.alg.components(g);
 * // => [ [ 'A', 'B', 'C', 'D' ],
 * //      [ 'E', 'F', 'G' ],
 * //      [ 'H', 'I' ] ]
 * ```
 *
 * @param {Graph} g - The graph to find components in.
 * @returns {NodeID[][]} An array of components, each of which is an array of node IDs.
 *
 * @remarks This function takes `O(|V|)` time.
