Provides a method wrap_func(func, debug, print_env). If debug is off,

the StampedLogger is initialized.  If debug is on, or the
StampedLogger errors, func is run in a try-except block.  If there's
an error, it's printed to the web page, along with the environment if
print_env is on.
Based off Michael McLay's subscribe script, but I wanted to avoid as
much code duplication as possible, which led to this strategy.
