Title: Fix chebpts rescale

This is to address #1202. Now the barycentric weights are rescaled.
```
>> [x, w, v] = chebpts(4, 1)
x =
-0.9239
-0.3827
0.3827
0.9239
w =
0.2643 0.7357 0.7357 0.2643
v =
-0.4142
1.0000
-1.0000
0.4142
```
@nickhale What is the benefit of such a rescaling? If there isn't much we gain, shall we just leave the code as it is but change the help text?
