JSON is a light-weight, language independent, data interchange format.
See http://www.JSON.org/
The files in this package implement JSON encoders/decoders in Java.
It also includes the capability to convert between JSON and XML, HTTP
headers, Cookies, and CDL.
This is a reference implementation. There are a large number of JSON packages
in Java. Perhaps someday the Java community will standardize on one. Until
then, choose carefully.
