/**
* Returns the differential entropy for a Laplace distribution with location `mu` and scale `b`.
*
* ## Notes
*
* -   If provided `b <= 0`, the function returns `NaN`.
*
* @param mu - location parameter
* @param b - scale parameter
* @returns entropy
*
* @example
* var y = entropy( 0.0, 1.0 );
* // returns ~1.693
*
* @example
* var y = entropy( 5.0, 2.0 );
* // returns ~2.386
*
* @example
* var y = entropy( NaN, 1.0 );
* // returns NaN
*
* @example
* var y = entropy( 0.0, NaN );
* // returns NaN
*
* @example
* var y = entropy( 0.0, 0.0 );
* // returns NaN
