makeRegSize

 makeRegSize : computes the projections lengths after rotating.
 The mask is rotated by the angle in props.Orientation. 

 INPUT :
       mask : masked region of interest
       props : contains information about the orientation of the region
 OUTPUT:
       L1 : projection length of region on the major axis
       L2 : projection length of region on the minor axis
