6     * Block CPR is a module to provide weighted role specific content. Drupal allows block access per role,
7     * but what if a user has 1 or more roles beside authenticated? Odds are, you would see two or more blocks as
8     * each one matches a role the user has. This module gets around this by allowing weights to decide which order
9     * the roles are checked. The first match is the one that shows. Each roles gets its own content.
