 * Problem:
 * Return the lowest index at which a value (second argument) should be inserted into an array (first argument) once it has been sorted.
 * The returned value should be a number.
 * For example, getIndexToIns([1,2,3,4], 1.5) should return 1 because it is greater than 1 (index 0), but less than 2 (index 1).
