duplicate tensor labels lead to exatensor hanging

[aspgomes]

while debugging code in dirac, i've noticed that if different tensors are initialized with the same label/string identifier, the code hangs.

it perhaps would be nice if exatensor/talsh catch that as an error.

Andre, could you clarify what you mean by "initialized with the same label/string identifier"? Did you mean when they are created by exatns_tensor_create() under the same name instead? Like, exatns_tensor_create(ltens,'Tensor') and then exatns_tensor_create(rtens,'Tensor')?

[aspgomes]

yes, i mean precisely what you wrote.
