// Description:     Standalone App for the ZPU test application.
//                  This program implements a loadable appliation which can be loaded from SD card by
//                  the ZPUTA application. The idea is that commands or programs can be stored on the
//                  SD card and executed by ZPUTA just like an OS such as Linux. The primary purpose
//                  is to be able to minimise the size of ZPUTA for applications where minimal ram is
//                  available.
