* `build` nunjucks filter builds a URL, starting from a base URL and adding parameters to the query string, or to the path if an array of path-worthy properties is specified as the first argument. After the path array if any, the rest of the parameters are objects whose properties are applied to the query string or path as appropriate. The last object wins, so it is easy to override filters in a URL
* `aposPageRange` is a simple nunjucks helper that returns a suitable range of pages for the pager. This is a workaround for some nunjucks bugs, ideally this would all be in pagerMacros.html
* apos.sanitizeInteger correctly maps NaN to the default
* Basic CSS for the pager
* First unit tests for this module, all of which test the daylights out of apos.build
