Python-banyan

I have renamed self.context to self.my_context in the base classes and examples to allow the Banyan base classes to participate in multiple inheritance applications.

No code was changed other than the rename.

This release affects banyan_base_aio.py only. When using a mac, the zombie exception is sometimes thrown by psutil. This ignores that exception.

Arduino Gateway and html updated for sonar support fixes.

This release addresses issue 5.

The method used to determine the local IP address involved having access to the Google DNS (8.8.8.8).
The code has been modified so that is no longer the case.

The updated code will allow successful IP address discovery even if there is no connection to the Internet.
Connection to the local router is still required, but the router does not need to be connected to the Internet.

You can now use an access point to provide the local IP address for standalone operations.
