Add binning algorithm control.

[samussiah]

Test notes

• Verify a new control labeled Algorithm appears in the Bins group of controls with these options:
  • Square-root choice
  • Sturges formula
  • Rice Rule
  • Scotts normal reference rule
  • Freedman-Diaconis choice
  • Shimazaki and Shinomotos choice
  • Custom
• Selecting any algorithm except Custom should effect these changes:
  • The algorithm returns the number of bins and the width of each bin.
  • The Quantity and Width inputs update accordingly.
  • The info icon updates with a link to an description of the algorithm.
• Verify the number of bins in the Quantity input matches the number of bars in the chart.
• Verify the width of each bin in the Width input matches the width of the bars in the chart.
• Most importantly, rigorously validate each algorithm. And I mean take that algorithm to town. Make it do work.
