An example for bullet list

The item marker is not shown because the default item marker is picked from the
math font and Neo Euler math font is not complete, so that marker is missing.

In the next few steps, I will show how to use a different item marker, so lets
not worry about it right now.
Create a dedicated first level bullet environment

Rather than tweaking the default itemize environment, it is easier to create a
new first-level bullet environment.
Use metapost to create a bullet marker
