Implement dynamic plugin change in ConfigDiff

[curran]

Requires changing configDiff.js to generate the correct sequence of actions to tear down the old component and set up a new one when the plugin changes in the configuration. This is necessary for switching dynamically between visualization types.

When the plugin property for a component changes, the following sequence of actions should be generated and executed in the runtime:

• Destroy the old component
• Create the new component by invoking the newly specified plugin
• Set all the values for fields on the previous component to the new component
