[Casa-framework] builtin tools

[Lindsey Davis]

Hi,

I have a question about the persistence of the builtin tools. It is
quite easy to do something like

cb = None

or

x = 6
cb = x

in Python.

What is the effect of overwriting a builtin tool. I know how to create
my own instance of a tool and call it whatever I want to, but how do
you expect your users to recover gracefully from this?

How does doing this affect the tasks that depend on a calibrator tool.
Do these task recreate a new if the builtin has been corrupted or is NOne or do
they fail ?
