Generate entity classes and method stubs from your mapping information.

If you use the <comment>--update-entities</comment> or <comment>--regenerate-entities</comment> flags your existing
code gets overwritten. The EntityGenerator will only append new code to your
file and will not delete the old code. However this approach may still be prone
to error and we suggest you use code repositories such as GIT or SVN to make
backups of your code.

It makes sense to generate the entity code if you are using entities as Data
Access Objects only and don't put much additional logic on them. If you are
however putting much more logic on the entities you should refrain from using
the entity-generator and code your entities manually.

<error>Important:</error> Even if you specified Inheritance options in your
XML or YAML Mapping files the generator cannot generate the base and
child classes for you correctly, because it doesn't know which
class is supposed to extend which. You have to adjust the entity
code manually for inheritance to work!
