Binning improvement project:

Programming part: I continued test step and finished short-term goal.

Research part:

1. We discussed "kernel smoothing on binning" several times and I provided a set of mass-frequency datasets for comparison study.

1. Ming and Shuo have separately generated "kernel density

estimation curve".

Ming, Shuo and Heidi did an excellent work on it and we might have achieved a great step on it. Since further study is needed, we are still not so sure.
