## Remez (exchange) algorithm.

Only six functions are available now.

Write the parameters: a and b, the interval endpoints; the degree of
the approximation; and the number N of gridpoints, in the white
subwindows. Then, click on one of the six functions buttons. You should
see the error function corresponding to a first set of trial extremal
points (blue lines). The true extremum [on the set of grid points]
is shown by a red line. By pushing several times on the "Next"
button, further steps of the exchange algorithm are shown.

Whenever you change a parameter, push again on a function button before
using the "Next" button.
