Testing sum_of_intervals function.
The function should accept an array of intervals,
and return the sum of all the interval lengths.
Overlapping intervals should only be counted once.
Intervals
Intervals are represented by a pair of integers in
the form of an array. The first value of the interval
will always be less than the second value.
Interval example: [1, 5] is an interval from 1 to 5.
The length of this interval is 4.
