Update task dependencies.
Remove clean task.

The clean task was the culprit as to why sometimes as files changes and
were automatically rebuilt it failed. Reviewing the gulp plugin it
actually deletes the folder and files but we shouldn’t need that. We
can just overwrite the files in dist folder.
Update comments.
Remove unnecessary examples.

The other column of examples is out of scope for this plugin for now.
If we want to add that in we always can at a later point. Lets keep
this focused.
