Is Lattigo completely single-threaded by default?

[Tokubara]

When I run a program, I notice using htop that only one core is being utilized. I'm wondering if Lattigo is entirely single-threaded by default (unless the user explicitly uses goroutines or sync)?

Yes, and structures above the ring package are not thread safe. But light copies (that only reallocate non-thread safe buffers) can be created with the ShallowCopy() method.
