@damienpontifex is it correct to say that this is a breaking change (non-backward compatible)?

If yes, please re-submit the PR for 2.1.3 branch instead.

[damienpontifex]

@wing328 I don't believe it to be a breaking change as it just provides another avenue for passing in the configuration value.
I would be happy to have more feedback from others who are using it if it is actually causing a breaking change.

Nice addition to the angular2 api. Doesn't seem a breaking change to me. should be completely backward compatible.

@wing328 @Vrolijkx just quickly added a note in the readme of how to set the custom base path. Let me know if there is any other sort of documentation we would normally add to these.
