Handling namespaces separated in full qualified names

[schaumb]

The types/statements are handled together with their namespaces. It would be handy if the user could go to the namespace definitions/declarations, and it can be seen where are used the namespaces.

namespace A { // here it can be shown a list with the main function first line because there is a usage
  void b() {}
}

int main() {
 A::b();
 // [A]::[b()];
 // [A] connected to the namespace
 // [b()] connected to the function declaration
}

using Namespace1::Namespace2::function;
// using [Namespace1]::[Namespace2]::[function];
