Fixed typo in ChopLib
Fixed suppression of stdout output when using fileout or jsonout -- not sure how this was missed
Added jsonutils to external libraries contains custom json encoders to handle non-default types
Changes to metacap to make it a bit more malleable

-Changed stream mode to be default - added bulk mode (-b) to do what it was before
-Made text output more human friendly
-Unified JSON output so it has one high-level hierarchy
-Added quiet mode so that text output is limited to only the summary (does not affect json output)
