 QGisIface is an abstract base class (ABC) that specifies what publicly available features of QGIS are exposed to third party code and plugins. QgisInterface is an concrete implementation of this ABC. The preferred way to carry out operations on QGIS is via the QGisInterface. An instance of the QgisInterface is passed to the plugin when it loads. Please consult the QGIS development team if there is functionality required in the QGisInterface that is not available.

-This is the class that provides the 'glue' between your custom application logic and the QGIS application. You will see that a number of methods are already implemented for you - including some examples of how to add a raster or vector layer to the main application map canvas. This class is a subclass of QgisPlugin which defines required behaviour for a plugin. In particular, a plugin has a number of static methods and members so that the QgsPluginManager and plugin loader logic can identify each plugin, create an appropriate menu entry for it etc. Note there is nothing stopping you creating multiple toolbar icons and menu entries for a single plugin. By default though a single menu entry and toolbar button is created and its pre-configured to call the run() method in this class when selected. This default implementation provided for you by the plugin builder is well documented, so please refer to the code for further advice.
