* can be reused throught the resolver.
*
* (Yes, I'd rather have called this class FileURI, but
* given that a jave.net.URL is returned, it seemed...even more
* confusing.)

/**
* Construct a file: URL for a path name.
*
* URLs in the file: scheme can be constructed for paths on
* the local file system. Several possibilities need to be considered:
*
*
*
* - If the path does not begin with a slash, then it is assumed
* to reside in the users current working directory
* (System.getProperty("user.dir")).
* - On Windows machines, the current working directory uses
* backslashes (\\, instead of /).
* - If the current working directory is "/", don't add an extra
* slash before the base name.
*
*
* This method is declared static so that other classes
* can use it directly.
*
* @param pathname The path name component for which to construct a URL.
*
* @return The appropriate file: URL.
*
* @throws MalformedURLException if the pathname can't be turned into
* a proper URL.
