Implement Task AB#3095678 - Define Measurement Script API

[mikeprosserni]

What does this Pull Request accomplish?

This PR defines the NiPanel interface class, with the methods that the user's measurement script will call.

Why should this Pull Request be merged?

This is the first step towards implementing the PythonPanel client API. Note that implementing the methods connect(), disconnect(), set_value() and get_value() will be done in subsequent PRs.

What testing has been done?

Two basic unit tests were added. One test calls each of the four methods directly, and the other test uses a with statement to call connect() and disconnect() automatically.
