Direct component communication example

[ceremcem]

Note to myself: Add the direct component communication examples:

• Simple implementation: Playground
• With namespace component: Playground
  • Problem: Reaching data and triggering events outside <namespace /> component is not possible at the moment: Playground
    • Discussion: (gitter conversation)
