/**
* Returns the index of the first element in a sorted strided array which is greater than a specified search element.
*
* ## Notes
*
* -   The input strided array must be sorted in ascending order.
* -   If unable to find an element which is greater than the search element, the function returns `-1`.
*
* @param {PositiveInteger} N - number of indexed elements
* @param {*} searchElement - search element
* @param {Collection} x - sorted input array
* @param {integer} strideX - stride length
* @returns {integer} index
*
* @example
* var x = [ 1.0, 2.0, 2.0, 3.0 ];
*
* var idx = gindexOfGreaterThanSorted( x.length, 2.0, x, 1 );
* // returns 3
