$totalparameterregion

$totalparameterregion is a total command to assign arranges within one command. It is conflicted with commands $totalregion + $ranges (RayTracing) + $parameters (RayTracing). The usage is

$totalparameterregion
N_region
$x_{L}$  $x_{R}$  $y_{bottom}$  $y_{top}$  $n_{r}$  $\alpha$ 
$x_{L}$  $x_{R}$  $y_{bottom}$  $y_{top}$  $n_{r}$  $\alpha$ 
 ...
 ...   total N_region
 ...
 $x_{L}$  $x_{R}$  $y_{bottom}$  $y_{top}$  $n_{r}$  $\alpha$  

 $x_{L}$  : left range of x  (unit cm !)
 $x_{R}$  : right range of x  (unit cm !)
 $y_{bottom}$ :  bottom range of y (unit cm !)
 $y_{top}$: top range of y (unit cm !)
 $n_{r}$: refractive index
 $\alpha$:  absorption coefficient
