<h3>Statistics Fixes</h4>
<p>Miscellaneous Bugfixes for Statistics Text.  Footnote issue also resolved in a separate pull request by Phil that will require regression testing. 
<ul>
<li>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</li>
<li>Table headers modified inside Try It features and globally to always have bold headers</li>
<li>Request for Stats Lab Features to break on it's own separate page</li>
<li>Table numbers inside example were starting with 1.0 instead of 1.1</li>
<li>Generic Note header smaller font applied into deeper places where they are being used, i.e. Stats Lab, Example features, etc</li>
<li>Calculator header specificity increased to take care of it displaying in problems and solutions of examples</li>
<li>Bringing It Togther EOC collation classes created for upcoming extraction of content away from Practice/Homework Sections</li>
<li>Figure solutions numbering rebooted to be displayed.  Numbering.less change required for this. Commented on file to remove entire block during refactor push</li>
