Statistics Fixes for Numbering, Example headers breaking and miscellaneous fixes

Statistics Fixes
-------

Miscellaneous Bugfixes for Statistics Text.  Footnote issue also resolved in a separate pull request by Phil that will require regression testing. 

- Example header (bumper) was separating from body and breaking awkwardly. Fix was put in place to allow a nice break with examples.  Tested across entire text
- Table headers modified inside Try It features and globally to always have bold headers
- Request for Stats Lab Features to break on it's own separate page
- Table numbers inside example were starting with 1.0 instead of 1.1
- Generic Note header smaller font applied into deeper places where they are being used, i.e. Stats Lab, Example features, etc
- Calculator header specificity increased to take care of it displaying in problems and solutions of examples
- Bringing It Togther EOC collation classes created for upcoming extraction of content away from Practice/Homework Sections
- Figure solutions numbering rebooted to be displayed.  Numbering.less change required for this. Commented on file to remove entire block during refactor push


Testing
-------

- [ ] Verify end-of-chapter/book solutions (with figures) in all OSC books have a "sane" number
