Replacements are trivial, but please check very carefully if I didn't make a logic mistake.

Per in person discussion, the trivial comments were:

• Check the spacing around binary operators;
• Update copyright lines to look like the example in https://github.com/LSST/templates/blob/master/CopyrightHeader.cc (ie, with "AURA/LSST").

Other than that, good to merge. Nice improvement in readability over boost::lambda.

Merged after successful CI build.
One minor change was made to the code since review. A unit test (testProcessCcd.py in pipe_tasks) failed due to numerical precision differences. The boost version actually casted intermediate results to float and the new solution did not. I added the casts for now, but will create a new ticket to investigate the best solution.
