Moved some utilities to TensorMeta.h to make it easier to reuse them accross several tensor operations.
...
Created the TensorDimensionList class to encode the list of all the dimensions of a tensor of rank n. This could be done using TensorIndexList, however TensorIndexList require cxx11 which isn't yet supported as widely as we'd like.
