+The `sourcepath()` function determines the path of the currently executed
+ucode script file, optionally only the directory portion.
+
+By specifying the a depth parameter, the owning files of functions further
+up the call stack can be determined.
+
+Returns a string containing the path (or directory) of the running ucode
+source file.
+
+Returns `null` if the path is indeterminate.
