Function flag_algebra::density::count_split_tabulate

pub fn count_split_tabulate<F: Flag>(
    type_size: usize, 
    f1_vec: &[F], 
    f2_vec: &[F], 
    g_vec: &[F]
) -> Vec<CsMat<u64>>

Returns a vector m of length g_vec.len() of f1_vec.len()xf2_vec.len() matrices such that m[i][j,k] is equal to count_split(type_size, f1_vec[j], f2_vec[k], g_vec[i]).

This more efficient than iterating count_split.

The matrices are in CSR form.
