Simple log class (oolog): Generate logs that are outputted to file or a page

This class generates logs that can be outputted either to either a file and/or to the current Web page.

When outputting to the current page to browser it supports html tags. Printing multi line Messages are no problem.

When writting the log to a file it can start by truncating the file or appending the new log lines at the end of an existing file.

In debug mode, the class marks the log output to notice the lines being added as debug mode.

For error messages (if needed with auto-exit) the ALL flag can be used to tell the class to output the log to either the file and the current page.
