JSON to CSV converter in Golang.
Note: at this time, this converter doesn't implement the full JSON spec. (it doesn't currently handle arrays of scalar values, only arrays of map[string]interface{})
jcgo reads JSON from the file specified as a command line argument, parses the JSON, and writes the data to a CSV file.
