/**
 * Returns a set of media queries that resizes a property (or set of properties) between a provided fromSize and toSize. Accepts optional minScreen (defaults to '320px') and maxScreen (defaults to '1200px') to constrain the interpolation.
 *
 * @example
 * // Styles as object usage
 * const styles = {
 *   ...fluidRange(
 *    {
 *        prop: 'padding',
 *        fromSize: '20px',
 *        toSize: '100px',
 *      },
 *      '400px',
 *      '1000px',
 *    )
 * }
 *
 * // styled-components usage
 * const div = styled.div`
 *   ${fluidRange(
 *      {
 *        prop: 'padding',
 *        fromSize: '20px',
 *        toSize: '100px',
 *      },
 *      '400px',
 *      '1000px',
 *    )}
 * `
 *
 * // CSS as JS Output
 *
 * div: {
 *   "@media (min-width: 1000px)": Object {
 *     "padding": "100px",
 *   },
