# Pass the container name, ID variable name, and options with those names 
# surrounded by ## on either side, and this function will replace those, 
# closing the string and referring to a javascript variable in each place
#
# An example of when it's useful: Suppose you have a set of lists on screen 
# with some items. You periodically want to refresh the items for one of 
# the lists, and you don't want to generate the same function for each list
# in the page. Instead, you'd rather just have one function and pass the ID 
# of the list to it, and figure out the DOM ID and route based on the ID
# passed to the javascript function.
