// Tests SimpleFunction.asm in the CPU emulator.
// In particular, tests how the assembly implementation of the 'function'
// VM command initializes local variables, and how the assembly implementation
// of the 'return' VM command handles the return value, SP, LCL, ARG, THIS, and THAT. 
// Before executing the code, initializes the stack pointer and the pointers of some
// of the memory segments, and sets some values in the argument segment.
