ParseMultiArgs generates a ValueSet from multi value query parameters.

WherePart returns the part of the where clause between parens, as in: ( geography_code IN ( ..

ValueRange holds the low and high values for a range.

ValueSet holds all the single values and ranges for a for a multi-valued query parameter.

When operating on a Single, the value of s on return can be: nil - delete this Single ptr to a new value - changes this Single ptr to the current value - does not change this Single Similarly when operating on a Range, the value of l and h on return can be: nil - delete this Range ptrs to new values - change this Range ptrs to current values - does not change this Range See the example changeCallback in where_test.go.
