 * This little class records how long it takes each WordPress action or filter
 * to execute which gives a good indicator of what hooks are being slow.
 * You can then debug those hooks to see what hooked functions are causing problems.
 * 
 * This class does NOT time the core WordPress code that is being run between hooks.
 * You could use similar code to this that doesn't have an end processor to do that.

 * Instead, the aim is to have a simplified function that's easy to read and that uses
