Interactive plotting of solutions of a differential equation : `interactive_plotode interactive_odeplot`

Let *f* (*t*, *y*) be an expression depending of two
varaiables *t* and *y*.

`interactive_plotode(f(t,y),[t,y])` draws the tangent field
of the differential equation *y'* = *f* (*t*, *y*) in a new window.
In this window, one can click on a point to get the
plot of the solution of *y'* = *f* (*t*, *y*) crossing through this point.

You can further click to display
several solutions. To stop press
the `Esc` key.

Input :
`interactive_plotode(sin(t*y),[t,y]) `

Output :
`The tangent field is plotted with the
solutions of y'=sin(t,y) crossing through the points defined by
mouse clicks`
