* + 'logtofile' (log track log to file)
* + 'logfulltofile' (log full log array to raw serialize file)
*
* Note: You are not accessing these variables directly
* What happens is these variables are stored inside a protected
* array named common, when you get/set these variables, PHP5
* sees that they do not exists and then sends them to __set/__get
* functions, it is there where they are picked up and shoved
* back or from the array.

/**
* That's not all of what this class file has to offer
* Play around with it and you really see the power you can
* get from out of this class.
*
* The debugging is especially amazing, You can grab query intensity
* levels from the mysql log array, the class also logs every single move
* it makes to a serialized entry to a raw log file!
*
* Soon I will add a mysqli layer for this class, note the one final class
* and also I will make a debug layer complete with pie graphs and
* optimization solutions!
