Feature idea: function to check if values lay in domains of transformation

[scheidan]

As an additional feature it would be nice if we could use a transform to check if the provided inputs are legal.

For example

in_domain(t, y)

would return true if all values of y lay in the domains specified by t.

Such a function would make it convenient to check user provided arguments (i.e. model parameters).

Maybe this could be introduced when dealing with #24 or #64.

Great idea, thanks for suggesting it. I will implement this.
