The route helper functions are fairly well isolated from the rest of BaseService, with a few convenient entry points. They are easier to test in isolation. The way the code was written before, `pathToRegexp` was invoked once for every request, which seems inefficient. `route` was validated when it was used, though it seems more helpful to validate it up front. This breaks out `_makeFullUrl`, `_regex`, `_regexFromPath` into new helper functions `makeFullUrl`, `assertValidRoute`, `prepareRoute`, and `namedParamsForMatch`. It adds validation to route, and updates the services without patterns to include one, in order to pass the new validation rules.
