To filter a "box" spatial distribution by fissionable material, specify
"fission" tag instead of "box". The ``parameters`` should be given as six
real numbers, the first three of which specify the lower-left corner of a
parallelepiped and the last three of which specify the upper-right
corner. Source sites are sampled uniformly through that parallelepiped.
For a "point" spatial distribution, ``parameters`` should be given as
three real numbers which specify the (x,y,z) location of an isotropic
point source
