symmetrize_measure evolution strength

[Steven Dalton]

How should the symmetrize_measure parameter be interpreted in the evolution strength function? https://github.com/pyamg/pyamg/blob/master/pyamg/strength.py#L471

Applying the distance filter can still result in a structurally non-symmetric measure. https://github.com/pyamg/pyamg/blob/master/pyamg/strength.py#L782

Hey Steven,

Sorry for the delay in responding.  That appears to be a bug.  The symmetrize if-statement should be below the distance measure if-statement so that the final result of the routine is always symmetric, if symmetrize==True.

I just committed a change to the main branch to fix this.

Thanks for finding it!
