This page will look up the names and numeric ids of all the user's symbol lists.
Note: Normally, we only display the symbol list name to the end user, not the id. Internally we only use the id. If the user saves a strategy, we save the list's id number in the strategy, not the list's name. Changing a list's name will have no effect on the strategy.
On error, the result will be empty.
On success there will be a series of lines. The first line will contain the number of lists. (This is redundant, but may be helpful.) After that there will be one line per symbol list. Each line will contain the list's id number followed by a comma, followed by the list's name.
