IsoCostListN

This method calculates an isochrone from node, which extends until the first N nodes in NL has been reached.

If MaxCost has been set, it may stop sooner.

Result is returned in IL as a sorted index into NL. Length of IL may be < N, if not all nodes in NL is reached.

Example:

NL = {100, 200, 300, 400, 500, 600}

N = 3

cost(100) = 32

cost(200) = 45

cost(300) = 103

cost(400) = 77

cost(500) = 80

cost(600) = 10

Output: IL = {5, 0, 1}

Cost of index 5, 0 and 1 is 10, 32 and 45.
