/** @todo Implement traceStack. 
 *
 * This functions starts a strack trace that prints the frame address, frame pointer, 
 * return address, the specified number of local variables, and the specified number 
 * of parameters for each frame on the stack.   The stack trace should not include
 * the frame of the traceStack function itself or the <code>main()</code> function
 * that called the recursive function. 
 *
 * The function first prints a header for each column in the stack trace using the titles
 * FrameAddr, FramePtr, ReturnAddr, Parm1, Parm2, ... and Local1, Local2, ... 
 * on a single line. Note that the parameters should be printed in the order they appear
 * in the function definition.
 *
 * The frame address is printed as "%p" while the other values are printed as "0x%08x".  
 * There should be four spaces between each column.
 *
 * This function identifies the top of the stack and to determine the first frame pointer.
 * The function then calls the traceNext function to recursively print the frames on the
 * stack.

/** @todo Implement traceNext.
 *
 * This function performs the stack trace one frame at a time.  It prints a line 
 * with information about the current stack frame, then recursively calls itself 
 * with the frame pointer of the next stack frame to print.  
 * It stops when there are no more stack frames to print.
