-/* Utility class that uses d3.bisect to find the index in a given array, where a search value can be inserted.
-This is different from normal bisectLeft; this function finds the nearest index to insert the search value.
-
-For instance, lets say your array is [1,2,3,5,10,30], and you search for 28. 
-Normal d3.bisectLeft will return 4, because 28 is inserted after the number 10.  But interactiveBisect will return 5
-because 28 is closer to 30 than 10.
-
-Unit tests can be found in: interactiveBisectTest.html
-
-Has the following known issues:
-   * Will not work if the data points move backwards (ie, 10,9,8,7, etc) or if the data points are in random order.
