Update interface codebase

Browse Source 
The interface layout selection has been updated to support the interface option.
The interface option stores which data that needs to be plotted for each
devices.

The plot drawing code now supports the reverse plotting option.

The interface uses the ring buffer, the updated version of
the layout computation and plots the data specified by the interface options.
