Right now, we have

UniTensor.Contract() which contract two UniTensors.
UniTensor.Contract() which contract multiple UniTensors. This might be confusing to users. We should merge these APIs.

We should first think about what the new API should look like.

This is to confirm that all following codes work properly. Please merge it into the master branch.

cytnx.Contract(A, B)
cytnx.Contract([A, B])
cytnx.Contract([A, B, C])

Question: Do we want to depreciate cytnx.Contract(A, B) and only support `cytnx.Contract([A, B])' in the future?
