Provides circles in math mode that can be used for the nextstep
operator of temporal logic, in conjunction with `\Box` and
`\Diamond` (latexsym) or `\square` and
`\lozenge` (amssymb). LaTeX circles `\circ` and
`\bigcirc` are not of the right size. The circles are
taken from the font `lcircle10`. The package contains some hacks to
approximate the right size and this solution is definitely not
sufficient to give a high quality output.
