 * 
 * Gaalop uses a float array, and gaalet its multivectors which actually are arrays too.
 * What happens at the optimization to Gaalet:
 * We have a GaalopIndex, this index is set. Every blade has its position. This GaalopIndex must 
 * be transformed into a GaaletIndex. 
 * 
 * It was just handier for programming and less confusing.
