* Returns an array with the following keys:
* - base_path
* - base_url
* - css: an array of filenames
* - js: an array of filenames
* - inline_css: an array map of content ID to inline CSS content (not including <style> tag)
* - inline_js: an array map of content ID to inline JS content (not including <script> tag)
* - inline_head: an array map of content ID to arbitrary inline HTML content (typically
* <style>/<script> tags); it must be embedded within the <head> element
*
* All keys are optional.
*
* Ideally, you should store static assets in filenames that are returned via the normal css/js
* keys. However, the inline asset elements are useful when integrating with 3rd-party
* libraries that require static assets that are only available in an inline format.
*
* The inline content arrays require special string array keys: the caller of this function
* will use them to deduplicate content. This is particularly useful if multiple instances of
* the same asset provider are used. Inline assets from all collectors are merged together into
* the same array, so these content IDs effectively deduplicate the inline assets.
