* Returns the mode of a Kumaraswamy's double bounded distribution.
*
* ## Notes
*
* -   If `a <= 0` or `b <= 0`, the function returns `NaN`.
*
* @param a - first shape parameter
* @param b - second shape parameter
* @returns mode
*
* @example
* var v = mode( 1.5, 1.5 );
* // returns ~0.543
*
* @example
* var v = mode( 4.0, 12.0 );
* // returns ~0.503
*
* @example
* var v = mode( 12.0, 2.0 );
* // returns ~0.94
*
* @example
* var v = mode( 1.0, 1.0 );
* // returns NaN
*
* @example
* var v = mode( 1.5, -0.1 );
* // returns NaN
*
* @example
* var v = mode( -0.1, 1.5 );
* // returns NaN
*
* @example
* var v = mode( 2.0, NaN );
* // returns NaN
*
* @example
* var v = mode( NaN, 2.0 );
* // returns NaN
