HighestInterval

/// <summary>
/// Given a set of entries, each containing a time index and a int count
value,
//class Entry
//{
//time:int
//count:int
//}

//write a function that will give the time interval with the highest
count together,

//ie,
//if we had entries
//100, 2
//100, 1
//110, 10
//200, 4
//1000, 3
//1200, 8

//and we ran something like
//int highestInterval(int interval_range)
//highestInterval( 50 )
//it would return 100, because in 100-150, you have counts 2, 1, and 10.
