prettyprint

This function takes the input text and returns a pretty-printed, multiline, indented version. It assumes that the input text is the output of a well-structured toString and forms a valid comma separated paren tree.

A comma separated paren tree is a string that contains a balanced number of quotation marks, parentheses and brackets.

For example, the string may take the form Class(field1=1, field2="text", field3=Struct(a=4, b=5)).
