TTcross with fixed rank

Email from a user:
------------------------------

I think there is a bug in the latest 1.0.15 version.
It is triggered when you want to get TT format of a tensor, meanwhile you want to set the rank to a fixed value.
It happens in line “TensorTrainVec.py” line 1256 – 1257

self.TT = Gnew
self.init = True

These two lines should be within “INCREMENTAL=True” rather than be out of the “if-else” statement.
Otherwise, when “INCREMENTAL=FALSE”, you get

"local variable 'Gnew' referenced before assignment"

I fix this by adding one-indents to those two lines, and it works fine.
