Mapstraction - Mar 2008 - Routing through LatLng points and other stuff

Hi to all!

Well, I''ve been trying to find a solution to route using known LatLng
points
- I already have the location position, all I needed was the actual route,
so I''ve put together an addition to the
"mapstraction-route.js". I''ve listed
it below, so maybe it would not be a bad idea to merge it to the trunk...

Also, I have a few other questions regarding the routing:

1) How to handle errors when the route is unknown?
* namely, when I use the coordinates from the
http://mapstraction.com/route.php?router=mapquest&map=mapquest example,
everything works fine, but when I use [42.426474, -83.492817] and
[42.279092, -83.764378], i get the "TypeError: this.location has no
properties"
* I''m not really sure it is Mapstraction error, but here it is, so if
anyone
can help....

2) MapstractionRouter.prototype.addAPI = function(api)
* one has to manually set " ProxyServerPath " to something appropriate
to
the proxy solution used (the one in the example is for PHP and I work with
Rails)
* anyway, it would be nice to overload that parameter in the API itself (so
one does not need to change the code of the "mapstraction-route.js"
when
getting the new version

OK, that is it for now, any help regarding these question appreciated!
