error in parameter default tutorial

[harrisonritz]

in parameter defaults tutorial, example is given for setting theta=0 by leaving it unspecified, saying that the default value is 0.

however, in the documentation on that page, the default appears to be 0.1.
This should be corrected, because people might try this method for setting theta=0.
