Write a program which contains an internal function which returns
the standard deviation from the mean of
an array of real values (make all variables visible to the internal
procedure by host
association). Note that if the mean of a sequence of values 
is denoted
by m then the standard deviation, s, is defined as:
To demonstrate correctness print out the standard deviation of the following numbers (10 of 'em):
5.0 3.0 17.0 -7.56 78.1 99.99 0.8 11.7 33.8 29.6
and also for the following 14,
1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0 10.0 11.0 12.0 13.0 14.0
