Install the current version of the database schema, and any other setup tasks.

Implementations of this hook must be declared in the module's .install file. The hook will only be called the first time a module is installed, and the module's schema version will be set to the module's greatest numbered update hook. Because of this, anytime a hook_update_N() is added to the module, this function needs to be updated to reflect the current version of the database schema.

See the Schema API documentation at http://drupal.org/node/146843 for details on hook_schema, where a database tables are defined.

Note that functions declared in the module being installed are not yet available. The implementation of hook_install() will need to explicitly load the module before any declared functions may be invoked.

Anything added or modified in this function that can be removed during uninstall should be removed with hook_uninstall().
