[Carpet] nPoints assertion

[Ian Hinder]

Hi,

There is an assertion in Recompose.cc (line 1137)

      assert (mynpoints.at(n) > 0);

which aborts my run when I run at low resolution on 16 processors.
Erik, you suggested this check might not be necessary, and indeed things
work fine with the assertion removed.  OK to commit a patch or should I
do more specific testing?
