/**
* 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.
