There is a bug in the second derivative of the normal log density at line 164 of +logdist\normal.m

**inverse** of the second derivative of the log density.

```
case 'info'
Y = 1/(Std^2)*ones(size(X));
```

should be changed to ```
case 'info'
Y = -1/(Std^2)*ones(size(X));
```

This is also misleading since information is the No files are attached
