Description

Two reason for removing this:
1. Xmipp wants to add h at the end of the symmetry string for using mirror to get projections and ended up with "c1 c1 c1h" in its input string and run as "c1" not "c1h", for example. This slows down the refinement.

2. Originally this feature is meant for relaxing symmetry constraint at later iteration. However, if higher symmetry is used at first, the Euler angles would be locked in the local minimal so it will need special perturbation not covered by our basic pipeline.

r17486 moves symmetry out in the python scipts.

Amber, please check if any myamiweb side need changing. If the command generated and parameter imported has no repeat, it should be o.k.

Anchi,
On the web side, the symmetry in the command line created appears as

--symmetry="D7 (z)" 

Is this correct? or does it need to be changed somewhere else?
