Added LB1 to LB2 route bridge

[glopezdiest]

Prompted by issue #159, here is a script that transforms the LB1.0 routes into the new LB2.0 format.

This script has the following arguments

• -r or --routes: which is the path to the routes file
• -s or --scenarios: which is the path to the scenarios file
• -e or --endpoint: which is the path of the endpoint file
