This program is a variation on "SineGenerator" by Christian Bauer, 
using most of his original code.

Modifications:

-The amplitudes and frequencies are now controlled logarithmically by 
sliders, since this is how the human ear works. 
-The "/10" checkbox was changed to a "/20" to give you better control 
over
frequencies.  
-The frequency range was extended to 22KHz, and although it may be 
debatable whether the output is a sine wave at high frequencies, the 
human ear hears only the fundamental harmonic, so it is OK...  
- The program actually calculates cosines now, so that when the phase 
is reset to zero, the output starts at 1, just so that at 22 KHz, it 
is a sequence of 1, -1, 1, -1 that is output instead of the 0, 0, 0, 
0... that the sines would have generated.  
- Previously, if the sum of the amplitudes of the sine waves was 
greater than 1, unpleasant distortions could be heard (due to 
saturation).  The code checks if the sum of the amplitudes is too 
high, and if so it normalizes it to 1.
