Added ability to create breakpoints to perform functions on the footnotes at certain screen sizes
Added ability to reset numbering of footnotes after each change in user-specified containing element
A little bit of extra cleanup
Updated REGEX to find footnotes with more escaped special characters
A little refactoring on the footnote initialization function
