[Insight-developers] A couple patches for the release branch

[Bradley Lowekamp]

Hello Matt,

I am trying to get a RC for SimpleITK 0.7 done ASAP. I ran into a couple bug in ITK causing segfault and valgrind defects.

Please merge the following commits into release:

    BUG: Fix uninitialized m_Spacing in SignedMaurerDistance
    
    If PrintSelf was called before execution not value had been assigned
    to the m_Spacing variable. This defect was detected by Valgrind on the
    SimpleITK dashboard.

    BUG: Don't print null bias field
    
    Printing the N4BiasFieldCorrection before execution was causing a
    segfault. Print "(null)" when null IVAR is encountered.
