The source code does not appears to use many Numeric/numpy functions so
it should be easy to convert to numpy. You can probably get away with by
just importing what it needs:
from numpy import array
The 'AbinitStructureViewer.py' is a little more complex because it uses
the old dtype with zeros(). So you will also have to import zeros as
well ('from numpy import array, zeros') *and* change those calls such as:
'zeros(3,Int)' to 'zeros(3,int)'
For more details about converting see:
