/**
 * Isolates a component by adding an isolation class name to the outermost
 * DOM element emitted by the component’s view stream.
 *
 * The isolation class name is generated by appending the given isolation `key`
 * to the prefix `$$isolation$$-`, e.g., given `foo` as `key` produces
 * `$$isolation$$-foo`.
 *
 * Isolating components are useful especially when dealing with lists of a
 * specific component, so that events can be differentiated between the siblings.
 * However, isolated components are not isolated from access by an ancestor DOM
 * element.
 *
 * Note that `isolate` is curried.
 *
 * @name isolate<Sources extends DomSources, Sinks extends DomSinks>(component: Component<Sources, Sinks>, key: string, sources: Sources): Sinks
 *
 * @example
 * import { empty } from '@motorcycle/stream'
 * import { createDomSource } from '@motorcycle/dom'
 *
 * const sources = createDomSource(empty())
 * const sinks = isolate(MyComponent, `myIsolationKey`, sources)
