zero-sized CFs #315

Allow min_matrix_radius to be set to zero, and then say that if no unit ends up in the CF, then there will be no CF for that unit. But that's going to make the rest of the code hard to write, because we'll either have to deal with CFs with empty matrices, or deal with CFs missing altogether. (As an example, the problem of zero-sized CFs arises in examples/joublin_bc96.ty.) Maybe it would be simplest to use a non-zero CF size, but with a mask making no unit visible; not sure.

Have SheetMask and CFMask.

Null cf support not implemented for plotting or for C code.

Also need to have an abstract Mask class to define interface.
