M2SCI function

mtlb_box - Matlab box emulation function

### Description

There is no Scilab equivalent function for Matlab `box` but it can be easyly replaced.

The function `mtlb_box([axes_handle[,val]])` is used by `mfile2sci` to replace `box([axes_handle[,va]]l)` when it was not possible to know what were the inputs while porting Matlab code to Scilab. This function will determine the correct semantic at run time. If you want to have a more efficient code it is possible to replace `mtlb_box` calls:

  - When called without input parameters, `mtlb_box()` may be replaced by `a=gca();if a.box=="on" then a.box="off";else a.box="on";end;`
  - If `axes_handle` is a character string, `mtlb_box(axes_handle)` may be replaced by `a=gca();a.box=convstr(axes_handle,"l");`
  - If `axes_handle` is a graphic handle `mtlb_box(axes_handle)` may be replaced by `if axes_handle.box=="on" then axes_handle.box="off";else axes_handle.box="on";end;`
  - If `axes_handle` is a graphic handle and `val` is a character string `mtlb_box(axes_handle,val)` may be replaced by `axes_handle.box=convstr(val,"l");`

Caution: `mtlb_box` has not to be used for hand coded functions.
