Investigate if get_nth can return the original type.

I have the feeling I can improve upon the get_nth function in the static dispatch. making returning variants and applying visitors. This way I can couple vieuw to certain data types for instance the length/duration field in the dmp-library. This should not be a flat string with seconds but should be converted by Qt into a duration like representation. This can only be done if I have some original knowledge of the type. Boost fusion still knows the type but i throw it away when getting the nth member for convenience.

Well this is not possible, We thought about it, but we have a runtime constant as a parameter and there is no way we can turn this in to a compile time constant before we enter the body. So there is no way to use this in the return type of our system. Therefore making it return the actual type is impossible. But to maintain flexibility the method now returns a boost::any. This might change to a boost::variant.
