[Insight-users] Mattes Mutual Information implementation

[Tim Allman]

I have been living with mutual information day and night for  a while. 
You can get more information about Normalised MI in D. Rueckert et al. 
IEEE Trans. Med. Imag., 18 712 (1999) and Mattes MI in Mattes et al IEEE 
Trans. Med. Imag., 22 120-128 (2003) and references contained therein.

If you understand the methods in the papers, the ITK classes start to 
make sense in spite of the poor documentation. It is undocumented but 
true that Mattes MI is not thread safe so you must set the number of 
threads it uses to 1. I don't know about the other.
