With this file we are going to assign the characteristics of this module.

• Application
  It's the identify code of our application
  ERPA in this case means ERPApplication
• Module
  It's the identify code of our module
  In this case ERPC means ERPCustomer module
• CurrentVersion
  Is the database version ( to manage the upgrade )
• DllVersion
  Return the dll version
• RegisterCountersAndCodes
  Allows you to register the Counters and the speaking codes
• Addon Allows you to attach an Addon to a document or batch of another module. The addon is a code that usually locks itself to a dataentry. It receives events like new, save, delete and allows you to add functionality from another module.
• RegisterPreferences
  Allow you to add a preference panel for this module
• CreateDBTables
  With method AddTable<mytable>([bool toExport = true]) we add the module tables to the framework.
  At first connection, if the table not exists, the framework will create the missing table.
  If the table is a temporary table, you can set the parameter to false. This way, when you export your database to xml, this table will not be exported.
• UpdateDBTables Here you can put the code to upgrade the database as add column, update values.
