"cluster" under "local example"

[shantenujha]

In http://radical-cybertools.github.io/entk/try_it_online.html

under "2. Local Example"

we say, "This example shows how to execute a task that writes "Hello World" to a file and download the file using Ensemble toolkit components."

1. We don't explain to the user why its called "local example". Pls mention that ".. it will execute a task on your local host machine and writes, "Hello World" to a file locally.
2. We go on to invoke a "cluster" handle under 2.2 Create a Resource Handle

This is going to confuse the user: they've just been told we're going to run/execute an example locally, and we suddenly expose them to a cluster.

Either explain better why we use "cluster" for resource handle or change to something that in the name is less disruptive. Make sense?
