/**
* Adjusts packages of all pages and removes name conflicts within a package
*
* Automatic linking requires that each linkable name have exactly one element
* associated with it. In other words, there cannot be two functions named
* foo() in the same package.
*
* This also adheres to php rules with one exception:
*
* <code>
* if ($test == 3) {
* define('whatever', 'this thing');
* } else {
* define('whatever', 'this other thing');
* }
* </code>
*
* phpDocumentor is not aware of conditional control structures because it
* would slow things down considerably. So, what phpDocumentor does is
* automatically ignore the second define and raise a warning. The warning can
* be eliminated with an @ignore tag on the second element like so:
*
* <code>
* if ($test == 3) {
* define('whatever', 'this thing');
* } else {
* /**
* * @ignore
* {@*}
* define('whatever', 'this other thing');
* }
* </code>
*
* If there are two files that contain the same procedural elements in the
* same package (for example, a common configuration file common.php), they
* will also be ignored as if they were in the same file. The reasoning
* behind this is simple. A package is an indivisible set of files and
* classes that a user will include in their code. Name conflicts must be
* avoided to allow successful execution.
*
* This function also plays the all-important role of calling
* {@link phpDocumentor_IntermediateParser::addElementToPage()} in order to add
* processed elements to their pages for Conversion.
