/**
* Returns the number of hours in a year according to the Gregorian calendar.
*
* ## Notes
*
* - By default, the function returns the number of hours in the current year (according to local time). To determine the number of hours for a particular year, provide either a year or a `Date` object.
* - The function's return value is a generalization and does **not** take into account inaccuracies due to daylight savings conventions, crossing timezones, or other complications with time and dates.
*
* @param value - year or `Date` object
* @returns number of hours in a year
*
* @example
* var num = hoursInYear();
* // returns <number>
*
* @example
* var num = hoursInYear( 2016 );
* // returns 8784
*
* @example
* var num = hoursInYear( 2017 );
* // returns 8760
