View source for Snip access cellset data

It would be nice to access data in a cell set like this:
<cpp>
filter[cellSet]=filterID;
</cpp>
to set the value of <tt>filter</tt> for all the cells in the <tt>cellSet</tt> to <tt>filterID</tt>, but unfortunately that's not possible.

The way to do this is:
<cpp>
cellSet filterSet(mesh,filterName,IOobject::MUST_READ,IOobject::NO_WRITE);

for(cellSet::iterator cell=filterSet.begin();cell!=filterSet.end();cell++)
filter[cell.key()]=filterID; 
</cpp>

This can be applied to <tt>cellSet</tt>s too.
