-# HORRIBLE HACK BUT WORKS :-) PR anyone?

-# Why?
-# `browsersteps_playwright_browser_interface.chromium.connect_over_cdp()` will only run once without async()
-# - this flask app is not async()
-# - A single timeout/keepalive which applies to the session made at .connect_over_cdp()
-#
-# So it means that we must unfortunately for now just keep a single timer since .connect_over_cdp() was run
-# and know when that reaches timeout/keepalive :( when that time is up, restart the connection and tell the user
-# that their time is up, insert another coin. (reload)

-# Groups tags

-## How it works
-
-Watch has a list() of tag UUID's, which relate to a config under application.settings.tags
-
-The 'tag' is actually a watch, because they basically will eventually share 90% of the same config.
-
-So a tag is like an abstract of a watch

-The concept here is to be able to switch between different domain specific problems to solve.
-
-- `text_json_diff` The traditional text and JSON comparison handler
-- `restock_diff` Only cares about detecting if a product looks like it has some text that suggests that it's out of stock, otherwise assumes that it's in stock.
-
-Some suggestions for the future
-
-- `graphical` 
-
-## Todo
-
-- Make each processor return a extra list of sub-processed (so you could configure a single processor in different ways)
-- move restock_diff to its own pip/github repo
