bycycle_00-Introduction figure legends

[sydney-smith]

The 2nd to last figure plotting burst characteristics being dependent on filter length and frequency range needs a legend to differentiate between the different conditions.

Also, a brief paragraph interpreting this figure along the lines of the tutorial takeaways would be useful.

Finally, I think the notebook should be broken up into sections with different subheadings. For instance: 1) conventional analysis, 2) drawbacks of conventional analysis
