Does the term, "v set" mean anything to anyone?
<p>I am using code that a friend wrote.  He uses the term "vset" to refer to calculation domains.  The vset has all information about the domain, like its dimension, etc.</p>

<p>In passing, he mentioned that vsets are a general concept, but I have not managed to find anything on them.  Does this term ring a bell for anyone?  If so, I would appreciate any explanation or direction to online resources!  Thanks.</p>
