kde.m calls figure(1), but it should not.

What steps will reproduce the problem?

1. Call figure(1).
2. Plot something.
3. Call figure(2).
4. call kde.m on some data without any output arguments.

What is the expected output? What do you see instead?

Expected result: kde plot appears on figure 2.
Actual result: kde plot appears on figure 1.

What version / revision of the product are you using? On what operating
system?

I am using the version from 
http://www.mathworks.com/matlabcentral/fileexchange/14034 under GNU Octave 
3.6.2 on Debian.

Please provide any additional information below.

This makes it difficult to view kde plots for multiple data sets.
