check whether array index is valid in Swift

WastingTimeOnStackOverflowTests.swift
// WastingTimeOnStackOverflowTests.swift Created by mason on 2016-09-18.
import XCTest
/// Measures performance of two different ways of checking whether an index is valid
/// for a given array (the variable "a" is an array of 1,000,000 unique strings, and
/// "val" is the index to be checked):
///
/// a.indices.contains(val)
/// vs:
/// val > 0 && val < (a.count - 1)
//
/// Each test checks the validity of 2,192 different integers, using one of the two
/// methods. The end result is that both ways are fast and any difference is extremely
/// marginal. (Hard to measure since it is so small, but the second way might be on the
/// order of 0.00000005 seconds faster.) Therfore, I will use the first (IMO less
/// puke-looking) method henceforth.
