 Usage:  xnew = glmmultshape(x,m,format)  
 
 Input:

  x                      n x r matrix, the predictor variables. x can 
                         be either in matrix format, then r=m*q, i.e. 
                         x consists of q nxm matrices. If x is in panel 
                         format, n=m*k. 
                         
  m                      number of alternatives. 
                         
  format                 either "panel" or "matrix", the format that 
                         the output should have. 
                         
 Output:

  xnew                   reshaped x matrix.
