Clarify the cost-matrix instruction.

The sentence uses id as a singular noun and does not clearly identify the source and destination sets. Refer to id values explicitly.

Proposed wording 
-* Get a traveling cost matrix in seconds from all the following ``id`` to all
-  the ``id``
+* Get a travel-cost matrix in seconds from all the following ``id`` values to
+  all ``id`` values.
