/**  HOWTO use it
*   Function created by: Mathieu Beausoleil
*
*   Put "CGUtilitiesFontSize" class on all container you want to apply the font change
*   To ignore a container, use the class "CGUtilitiesFontSizeIgnore"
*
*   Use CGUtilitiesFontSize(1) to add a pixel to the concerned container.
*   Use CGUtilitiesFontSize(1, bleh) to execute the "bleh" function after the modif.
