/** This function is used to load values from georges sheet in a quick way.
* The first time it loads the sheet and parse it with the readGeorges function
* provided by the user to read the value he wants. It'll generate a packed file
* that contains this values (using serialCont). The next launch, the function will
* only load the packed file and if some sheet have changed, it'll automatically regenerate
* the packed file.
*
* To use the loadForm(), you first have to create a class that will contains values for one sheet.
* This class must also implements 2 functions (readGeorges() and serial()) and 1 static function (getVersion())
*
* Extension file name for the packedFilename must be ".packed_sheets"
*
* Classical use (copy/paste this in your code):
// For each sheet in the packed sheet, an instance of this class
// is created and stored into an stl container.
// This class must be default and copy constructable.
