/**
  Binary search
  1. Array MUST be sorted already
  2. If the array has multiple elements with the same value the first instance
     in the array is returned e.g.
       [1,2,3,3,3,4,5].binarySearch(3);  // returns 2
     This means slightly more loops than other binary searches, but I figure
     it's worth it, as the worst case searchs on a 1 million array is around 20
  3. The return value is the index of the first matching element, OR
     if not found, a negative index of where the element should be - 1 e.g.
       [1,2,3,6,7].binarySearch(5);      // returns -4
       [1,2,3,6,7].binarySearch(0);      // returns -1
     To insert at this point do something like this:
       var array = [1,2,3,6,7];
       var index = array.binarySearch(5);
       if(index < 0)
         array.splice(Math.abs(index)-1, 0, 5); // inserted the number 5
