lperron@google.com	5700126591	added setup dependent transition times on the disjunctive class; renamed files with - in their names to _; plenty of changes in the base library and modifications in the rest of the code accomodate them; dropped support for vs 2010 by using the brand new c++11 iterators (for (int i : vector_of_ints) {}). This is so neat; removed SetCommandLines on the routing model. I added a temporary API with parameters. This API is not final and will change to its final version soon	2013-10-10 15:23:20 +00:00
