A program to calculate Pi to a user-specified number of digits.  The program
uses the identity

9/4 = 6 arctan(1/8) + 2 arctan(1/57) + arctan(1/239)

along with the Maclauren series for the arctangent function.

At the prompt in the window, enter a digit between 10 and 1,000,010 and the
program (eventually) returns that many digits of Pi.  The program can be 
interupted in progress to view or save digits thus far computed.  Computation
can then be resumed.

Author's warning:  The value of pi produced by this program has been
verified to 10,000 places.

Tested using a PowerMac 7100 running system 7.5.1.
