Classes implemented in headers

[PDoakORNL]

Sometimes its acceptable for templates to implement even very long methods in headers, the rest of the time it just makes the build slow and blurs interface and implementation.

This is a list of classes that should find themselves mostly in a .cpp soon. Unless explanations or objections are made.

• SPOSetScanner.h

SPOSetScanner is not really an important one. It is included in two builder cpp files.

My intention is for this issue to collect a list. I just was looking at that file when I wrote it. Didn't mean to single out SPOSetScanner.h as a serious one.
