[Feature Request] range class modification after initialization

[WenyinWei]

Hello Karl,

When I am utilizing the viennacl::range class to pick some parts of my code, I found that the range class only has const member functions which do not modify the instantiation. This causes some troubles when I want a flexible and concise code. Is it designed to make the instantiation const after the initialization?

Best regards,
Wenyin

I have come across this same problem and had to work around it.
