New Revision: 25985
URL: http://svn.gna.org/viewcvs/relax?rev=25985&view=rev
Log:
Massive speed up of the internal structural object add_model() method.
This speeds up the structure.add_model user function, as well as many internal
relax operations on
the structural object. Instead of using the copy.deepcopy() function to
duplicate an already
existing structural model, now new molecule container objects are created and
then the individual
elements of the original molecule container data lists are copied one by one.
This avoids copying a
lot of internal Python junk and hence the copying operation is now orders of
magnitude faster.
