## Description

The

 --show config=[glob] 

option to e.g. processCcd.py is very useful, but sometimes you find yourself wondering where that value came from. As discussed in http://community.lsst.org/t/how-do-i-get-the-history-of-a-configuration-object/162 you can get this information if you're willing to write some boiler-plate python but it'd be really nice to support via a --show
option. Something like

 --show configHistory[=glob]
