LifeCycle functions

A simple set of LifeCycle functions are called during the life span of e Component. They include:

• onCreated() - Called when a component has been detected in the DOM and instantiated.
• onPropChanged(oldProps, newProps, propName) - Called when the props in a component are changed as a result of modifying the DOM or by programmatically changing them.
• onDestroyed() - Called when the DOM structure of a component has been removed from DOM and the component needs to clean up.

1.0: onPropChanged won't be called under certain circumstances due to the mutation observer not being yet implemented. onDestroyed is not yet implemented as a result of removing elements from DOM.
