edit_curv - interactive graphic curve editor

### Calling Sequence

  `[x,y,ok,gc] = edit_curv(y)`
  `[x,y,ok,gc] = edit_curv(x,y)`
  `[x,y,ok,gc] = edit_curv(x,y,job)`
  `[x,y,ok,gc] = edit_curv(x,y,job,tit)`
  `[x,y,ok,gc] = edit_curv(x,y,job,tit,gc)`

### Parameters

- `x` : vector of x coordinates
- `y` : vector of y coordinates
- `job` : a character string formed by one to three of the characters 'a','x','y'
  - `'a'` : to add points to the edited curve
  - `'x'` : to modify x coordinates of the edited curve points
  - `'y'` : to modify y coordinates of the edited curve points
- `tit` : a vector of three character strings which give the curve legend
- `gc` : a list of graphic window parameters: `gc=list(rect,nax)`
  - `rect` : bounds of the graphics (see plot2d for details)
