Package csheets.ext.simple Description

Provides an example of how to build a simple extension. An extension is a class that extends the class Extension. CleanSheets dynamically loads all the extensions that it finds declared in the following property files: res/extensions.props and extensions.props. For the simple extension to be loaded at startup a line with the fully qualified name of the simple extension class must be present in one of the property files. The fully qualified name of the simple extension is: csheets.ext.simple.ExtensionExample
