/**
* Composes a URL query into a query string ready to be used as a part of a URL and returns it.
*
* Any characters that cannot be represented literally in a valid query string come out percent-encoded. The
* resulting query string never starts with "?".
*
* Because the characters in field named and field values are stored in their literal representations, the
* resulting query string is always normalized, with only those characters appearing percent-encoded that really
* require it for the query string to be valid and with the hexadecimal letters in percent-encoded characters
* appearing uppercased. Also, no duplicate fields are produced in the resulting query string (even if the object
* was constructed from a query string with duplicate fields in it) and "=" is added after any field name that goes
* without a value and is not followed by "=".
*
* @param bool $sortFields **OPTIONAL. Default is** `false`. Tells whether the fields in the query string should
* appear sorted in the ascending order, case-insensitively, and with natural order comparison used for sorting.
*
* @return CUStringObject The query string.
