Fixed FIXME: Csparse o dense - matrix products: now *all*  t() happen in C,
partly thanks to our new  chm_transpose_dense() function.
Csparse o Csparse : now have `boolArith` argument {not entirely finished}
New %&% : Boolean Arithmetic Matrix products      {not entirely finished}
C level: <sparse pattern> o <sparse numeric> : now return numeric "by default" / pattern "on demand"
