Err - Error logging helper

Err is meant to make adding runtime script error / engine crash logging to the filesystem easy so your users can send you log files if they are needed for debugging.

I still have some improving to do / adding features, but is open to feedback now. Specifically one thing I want to know is what is the best information to provide engine team so they can fix potential engine crashes saved to logs? Is what I included to log already correct?

Very useful for feedback! Thanks Pkeod. I plan on using this in the future.

It could be a simple, stupid question, but: Will Err log somehow automatically when there would be a crash? Or is it just for user to setup when the error() should appear?

	M.initialized = true
	if M.verbose then print("Err: err.init - Err is initialized.") end
	sys.set_error_handler(M.error_handler)
	if M.enable_crash_logging then
		crash.set_file_path(M.get_crash_path())
	end
	M.check_for_crashes()
	
end


function M.check_for_crashes()
	local dump = crash.load_previous()
	if dump == nil then
		print("Err: No crash dump found")
		return false
	else
		print("Err: Crash dump found, writing to log")


		local path = M.get_logging_path()
		local log = io.open(path, "a")

It does (I think…) but if you get a crash like this you want to save the actual crash file and also save debug symbols when you make a build so engine team can solve the bug.
