This module first checks to see if either Cpanel::JSON::XS or JSON::XS
is already loaded, in which case it uses that module. Otherwise it tries
to load Cpanel::JSON::XS, then JSON::XS, then JSON::PP in order, and
either uses the first module it finds or throws an error.
It then exports the "encode_json" and "decode_json" functions from the
loaded module, along with a "JSON" constant that returns the class name
for calling "new" on.
If you're writing fresh code rather than replacing JSON.pm usage, you
might want to pass options as constructor args rather than calling
mutators, so we provide our own "new" method that supports that.
