/*
  This function will search for all classes matching all IDs which are under
  #admonition_selector element and display/hide their content.

  State is saved in cookies so user doesn't lose his settings after page
  reload or changing pages.

  To make this feature work, you need to:
  - add checkbox to _templates/layout.html file with proper ID
  - in admonitions use proper class which matches above mentioned ID
