Import of terms adds Doubles

Hi @ikeigenwijs,

As per Drupal default functionality, we are able to add the terms in a vocabulary with the same names & this module follows the same. so i don't think its needed.

Agree with @viren18febs so closing this issue.

its a hierarchical tree structure it does not make sens to add the same term on the same level.

it invalidates the tagging principle " give me all the xx" xx being a tid
import result example.

eg:
ok
animal(tid 1) > horse(tid 2)
> dog(tid 3)

not ok
animal(tid 1) > horse (tid 2)
animal (tid 3)> dog (tid 4)

i hope it more clear so as way, there i no use case where the same term name on the same level makes sense in a hierarchical tree.
