//Class links

/* It should look like this: <span class="classlink">CIS105</span> */
/* After the page loads, the browser will make asynchronous requests to the class schedule for each tag. */
/* Tags are replaced with a link to that class in the schedule if it exists. */
/* Links are update automatically as responses are received in the background. */
/* */
/* NEW: Links now accept a parameter for Class Instruction Mode */
/* To use, the instruction mode must be the 2nd class of the span.  */
/* IE. <span class="classlink online">CIS105</span> Will create a link ONLY if there are */
/* CIS105 classes with the instruction mode IN (online) */
/* VALID MODES: 'online', 'print-based', 'in-person', 'mixed-media', 'hybrid' */
/* */
/* NOTE: If other classes are applied to the span, the mode must still be the 2nd class, */
/* regardless of where the 'classlink' class is. */
