Amnon Heiman 98a05c3bb9 API: Add the ratio_holder helper struct to ratio calculation 
Some of the APIs need to return a ratio.

The ratio_holder struct is a helper class that counts the total and the
sub totat, it implements the json::jsonable virtual class with a
to_json method that return the ratio.

The main usage of the sturct is with a map-reduce method.
