/**
 * This object represents a path as used by include_path or PATH
 * environment variable.
 *
 * This class has been adopted from the Java Ant equivalent.  The ability have
 * path structures in Phing is important; however, because of how PHP classes interact
 * the ability to specify CLASSPATHs makes less sense than Java.Rather than providing
 * CLASSPATH for any tasks that take classes as parameters, perhaps a better
 * solution in PHP is to have an IncludePath task, which prepends paths to PHP's include_path
 * INI variable. This gets around the problem that simply using a path to load the initial
 * PHP class is not enough (in most cases the loaded class may assume that it is on the global
 * PHP include_path, and will try to load dependent classes accordingly).  The other option is
 * to provide a way for this class to add paths to the include path, if desired -- or to create
 * an IncludePath subclass.  Once added, though, when would a path be removed from the include path?
 *
 * <p>
 * <code>
 * &lt;sometask&gt;<br>
 * &nbsp;&nbsp;&lt;somepath&gt;<br>
 * &nbsp;&nbsp;&nbsp;&nbsp;&lt;pathelement location="/path/to/file" /&gt;<br>
 * &nbsp;&nbsp;&nbsp;&nbsp;&lt;pathelement path="/path/to/class2;/path/to/class3" /&gt;<br>
 * &nbsp;&nbsp;&nbsp;&nbsp;&lt;pathelement location="/path/to/file3" /&gt;<br>
 * &nbsp;&nbsp;&lt;/somepath&gt;<br>
 * &lt;/sometask&gt;<br>
 * </code>
 * <p>
 * The object implemention <code>sometask</code> must provide a method called
 * <code>createSomepath</code> which returns an instance of <code>Path</code>.
 * Nested path definitions are handled by the Path object and must be labeled
 * <code>pathelement</code>.<p>
 *
 * The path element takes a parameter <code>path</code> which will be parsed
 * and split into single elements. It will usually be used
 * to define a path from an environment variable.

28		* solution in PHP is to have an IncludePath task, which prepends paths to PHP's include_path
29		* INI variable. This gets around the problem that simply using a path to load the initial
30		* PHP class is not enough (in most cases the loaded class may assume that it is on the global
31		* PHP include_path, and will try to load dependent classes accordingly). The other option is
32		* to provide a way for this class to add paths to the include path, if desired -- or to create
33		* an IncludePath subclass. Once added, though, when would a path be removed from the include path?
34		*
35		* <p>
36		* <code>
37		* <sometask><br>
38		*   <somepath><br>
39		*     <pathelement location="/path/to/file" /><br>
40		*     <pathelement path="/path/to/class2;/path/to/class3" /><br>
41		*     <pathelement location="/path/to/file3" /><br>
42		*   </somepath><br>
43		* </sometask><br>
44		* </code>
45		* <p>
46		* The object implemention <code>sometask</code> must provide a method called
47		* <code>createSomepath</code> which returns an instance of <code>Path</code>.
48		* Nested path definitions are handled by the Path object and must be labeled
49		* <code>pathelement</code>.<p>
50		*
51		* The path element takes a parameter <code>path</code> which will be parsed
52		* and split into single elements. It will usually be used
53		* to define a path from an environment variable.
