/**
* ProcessWire configuration paths and URLs
*
* #pw-headline Configuration paths and URLs (Paths class)
* #pw-summary Maintains lists of file paths or URLs, primarily used by the ProcessWire $config->paths and $urls API variables.
* #pw-summary-paths-only These properties are only useful when accessed from `$config->paths` as they are not HTTP accessible as URLs.
* #pw-summary-urls-only These properties apply only to the `$urls` or `$config->urls`. Do not use them with `$config->paths`.
* #pw-summary-pagination These properties apply only to the `$urls` or `$config->urls` and only when pagination is active for the current request.
*
* #pw-body =
* The Paths class is used by `$config->paths` and `$config->urls`. The `$config->paths` refers to server disk paths
* while `$config->urls` refers to web server URLs. All of the same properties are present on both, though several properties
* are only useful on one or the other (as outlined below). You can access a path or URL like this:
* ~~~~~
* $path = $config->paths->templates; // i.e. /path/to/htdocs/site/templates/
* $url = $config->urls->templates; // i.e. /site/templates/
* ~~~~~
* The `$config->urls` property can also be accessed more directly via the `$urls` API variable (in PW 3.x+):
* ~~~~~
* $url = $urls->templates; // i.e. /site/templates/
* ~~~~~
* For `$config->urls` (or `$urls`), if you prepend `http` to any of the property names (making it camelCase) it will
* return the full http/https URL rather then the relative URL:
* ~~~~~
* $httpUrl = $config->urls->httpTemplates; // i.e. https://domain.com/site/templates/
* $httpUrl = $urls->httpTemplates; // same as above
* ~~~~~
* You may optionally add your own properties as well. If you add a path/url without a leading slash “/” it is assumed to
* be relative to the `root` property. If it has a leading slash, then it is absolute.
* ~~~~~
* // add new urls properties
* $urls->set('css', 'site/templates/css/'); // relative to site root
* $urls->set('uikit', '/uikit/dist/'); // absolute
*
* // get properties that were set
* echo $urls->get('css'); // i.e. /site/templates/css/
* echo $urls->get('uikit'); // i.e. /uikit/dist/
* echo $urls->get('httpCss'); // i.e. https://domain.com/site/templates/css/
* echo $urls->get('httpUikit'); // i.e. https://domain.com/uikit/dist/
* echo $urls->httpUikit; // same as above (using get method call is optional for any of these)
* ~~~~~
* Do not set `http` properties directly, as they are dynamically generated from `urls` properties at runtime upon request.
*
* In the examples on this page, you can replace the `$urls` variable with `$config->paths` if you need to get the server path
* instead of a URL. As indicated earlier, `$urls` can aso be accessed at the more verbose `$config->urls` if you prefer.
