Wrap JSON to multi lines / Test ISJSON

install and usage

Packed ZPretty.xml installs routine ZPretty in any namespace.
calling $$Do^ZPretty(input,[filler],[newline]) returns a wrapped JSON string.
filler is the optional string for the indent, default = “ “
newline is optional, default = $C(13,10)
input accepts: JSON_String, JSON_Stream, %DynamicAbstractObject

^Pretty leaves all error trapping to you. So can use it as ISJSON check.

Set flat=$$Do^ZPretty(input,””,””) removes all formatting from input.
this could be useful to compare 2 different formatted JSON_Strings.
