hello, what will be the difference between this example and eclipse-che/che-theia#97
because it seems that if it's almost the same goal then we don't need an example as we've a real-world example on che-theia

We use plugin API in ours plugins, so sure these ones are examples how to use API.
In my opinion the difference is:

• user may not even know about which plugin he can use as sample for using corresponding API - but
  it's expected to search good example in che-theia-samples
• our plugins can contain a lot of logic vs for che-theia-samples case it's easier to find code you are interested in.

For current case I removed all che specific things, simplified as far as possible che-task plugin and represent it as sample.
But I don't mind - we can use che-task-plugin as sample, up to you.
