*
* Location and naming of modules
* All LAM modules are placed in lib/modules/ and are named ".inc".
* E.g. if you create a new module and its class name is "qmail" then the filename would be "qmail.inc".
* The class name of a module must contain only a-z, A-Z, 0-9, -, and _.
*
* You can avoid to override many functions by using {@link get_metaData()}.
*
* All module classes should extend the baseModule class.
