Author:

Message:

Making changes in domain to make sure unstructed grid work with new method of index distribution

+) Change the way define i_index and j_index of a domain
+) Remove some redundant attributes of domain
+) Adjust the way to calculate index distribution on server side

Test
+) Make some minor change to test_unstruct_complete to work with new XIOS
+) On Curie
+) All test pass and correct
