Voice controlled connected home

NLP seems to be a hard nut to crack. So taking a step back. I'll try to focus on low-hanging fruits. Some UI controls for playing media would be nice. Let's get that done first to keep up the motivation.

Natural Language Processing (NLP) deals with deciphering spoken language grammar and our understanding of the same. So far my app had two or three words commands. And coincidentally they followed a pattern. Like "play movie batman" or "switch lights on". I broke it down as:

1. The device that should handle the command
2. The function
3. Optional additional data required to perform the function

However, for mood light, this pattern breaks down. One is more likely to say "color device red" or "color all green". Got to spend some time thinking of a sensible algorithm to handle this possibly using NLP.

Now that mood lighting works with command line, the obvious next step is to add this capability in android app. I'm thinking of a color palette that the user can use to select a color of his choice. After all, there are a range of colors in between red, green and blue.

Added mood lighting support with RPi.
