/**
* Custom implementation of `visitable`
* Currently aims to be compatible and as close as possible to the
* actual `ember-cli-page-object` version
*
* Additions:
* 1. Injectable encoder, for when you don't want your segments to be encoded
* or you have specific encoding needs
* Specifically in my case for KV urls where the `Key`/Slug shouldn't be encoded,
* defaults to the browsers `encodeURIComponent` for compatibility and ease.
* 2. `path` can be an array of (string) paths OR a string for compatibility.
* If a path cannot be generated due to a lack of properties on the
* dynamic segment params, if will keep trying 'path' in the array
* until it finds one that it can construct. This follows the same thinking
* as 'if you don't specify an item, then we are looking to create one'
