#1 min() and max() functions for lybniz

[Luca Marturana]

Hi

Often I needed to study functions, like:

f(x) = max(log(x),e/x)

But with lybniz these functions didn't be displayed. So I modified the software a bit to add these function to the eval() instruction. I don't know if this is the better approach but it works for me. Attached here, there is the patch that I've made.

Thanks and congratulations for your software, it's very useful to study Analysis I :)
