Initial Commit -- added primary ipy NBs
Added TODO - make notebooks into standalone scripts
Most naive real-time plot of streaming data from IMU now works.\n\n Need to make more efficient now -- possibly with fixed size array
read_data.py now handles various cmnd line args for easier use

As for real-time data display...I may need to go back to bokeh for that or try something dirty e.g. slicing the last 1000 vals from a DataFrame, overwriting old vals,...
CL Args for plot_data and better real-time plotting

Basically just need to pass small n for num points.

Next fix is in changing how the plot and draw commands are called to increase performance and fix issue with retaining x values in plot

But Next commit should address data collection and classification issue!
