/**
* Returns a path to a certain resource within the Chamilo area, specifyed through a parameter.
* Also, this function provides conversion between path types, in this case the input path points inside the Chamilo area too.
*
* See $_configuration['course_folder'] in the configuration.php to alter the WEB_COURSE_PATH and SYS_COURSE_PATH parameters.
* @param string $type The requested path type (a defined constant), see the examples.
* @param string $path (optional) A path which type is to be converted. Also, it may be a defined constant for a path.
* This parameter has meaning when $type parameter has one of the following values: TO_WEB, TO_SYS, TO_REL. Otherwise it is ignored.
* @return string The requested path or the converted path.
*
* A terminology note:
* The defined constants used by this function contain the abbreviations WEB, REL, SYS with the following meaning for types:
* WEB - an absolute URL (we often call it web-path),
* example: http://www.mychamilo.org/chamilo/courses/COURSE01/document/lesson01.html;
*
* REL - represents a semi-absolute URL - a web-path, which is relative to the root web-path of the server, without server's base,
* example: /chamilo/courses/COURSE01/document/lesson01.html;
*
* SYS - represents an absolute path inside the scope of server's file system,
* /var/www/chamilo/courses/COURSE01/document/lesson01.html or
* C:/Inetpub/wwwroot/chamilo/courses/COURSE01/document/lesson01.html.
*
* In some abstract sense we can consider these three path types as absolute.
*
* Notes about the current behaviour model:
* 1. Windows back-slashes are converted to slashes in the result.
* 2. A semi-absolute web-path is detected by its leading slash. On Linux systems, absolute system paths start with
* a slash too, so an additional check about presence of leading system server base is implemented. For example, the function is
* able to distinguish type difference between /var/www/chamilo/courses/ (SYS) and /chamilo/courses/ (REL).
* 3. The function api_get_path() returns only these three types of paths, which in some sense are absolute. The function has
* no a mechanism for processing relative web/system paths, such as: lesson01.html, ./lesson01.html, ../css/my_styles.css.
* It has not been identified as needed yet.
* 4. Also, resolving the meta-symbols "." and ".." within paths has not been implemented, it is to be identified as needed.
*
* Example:
* Assume that your server root is /var/www/ ,
* Chamilo is installed in a sub folder chamilo/ and the URL of your campus is http://www.mychamilo.org
* The other configuration parameters have not been changed.
*
* This is how we can get most used paths, for common purpose:
* api_get_path(REL_PATH) /chamilo/
* api_get_path(REL_COURSE_PATH) /chamilo/courses/
* api_get_path(REL_CODE_PATH) /chamilo/main/
