Easy Debug: Handle errors and measure PHP execution time

Easy to use:
Just include the class file and it automatically replace the default error handler!


You can turn the display of error infos off & on at runtine, using
	debug::$on = false;
	debug::$on = true;
You can use it anytime in you code ;)

To use the chrono:
debug::chrono(); // set the timer
debug::chrono('your message'); // display your message & time elapsed since last chrono call
debug::chrono(true); // display a table with all messages & times

You can also use several chrono at the same time by passing chrono name as second argument:
debug::chrono( null, 'chrono1' ); // set the timer of chrono 1
usleep( 5000 );
debug::chrono( null, 'chrono2' ); // set the timer of chrono 2

debug::chrono( 'your message 1', 'chrono1' ); // display your message & time elapsed since last chrono 1 call
usleep( 5000 );
debug::chrono( 'your message 2', 'chrono2' ); // display your message & time elapsed since last chrono 2 call

debug::chrono( true, 'chrono1' ); // display a table with all messages & times of chrono 1
debug::chrono( true, 'chrono2' ); // display a table with all messages & times of chrono 2


Error display template:

$var1 = [value];
$var2 = [value];

Chrono display example:
----------------------------------------------------------------------
 -> message 1: x.xxxs
 -> message 2: x.xxxs
 -> message n: x.xxxs

chrono [name]
-------------------------------------------------------

-------------------------------------------------------
    1 - message 1                                x.xxxs
 x.xx - message 2                                x.xxxs
 x.xx - message n                                x.xxxs
