Return HashMap for a posted grid row.

This method is useful when processing a posted Dynamo Tools Entry Grid. It returns a map containing all of the field names and values of the row. Use map!.get("fieldName").toString() for strings. Use cast(Boolean, map!.get("fieldName") for Boolean true/false values including checkboxes. Use num(map!.get("fieldName").toString()) for numbers and integers.

ToDo add example

Return BBjTemplatedString from json containing template and hta(data) as strings.

 j! = new DTJsonObject()
 j!.put("tpl", "id:n(4), name:c(30*=)")
 j!.put("data", hta("1234United States"))
 rec! = DT.toTemplatedString(j!, "tpl", "data")
 ?rec!.fattr()
 ?rec!.getFieldAsNumber("id")
 ?rec!.getFieldAsString("name")

 ID:N(4), NAME:C(30*=)
 1234
 United States
