function Scatter = fake_ssm(x,seed)
% Fake SSM {B2,S1}-scatter generation. No tree structure produced.
% USAGE:
%   Scatter = fake_ssm(x)
% X - the input vector of parameters, dim: 6x1:
%   X(1) - number of samples for B2 scatter
%   X(2) - number of samples for S1 scatter
%   X(3) - mean of the normal distribution of B2 samples
%   X(4) - std of the normal distribution of B2 samples
%   X(5) - mean of the normal distribution of S1 samples
%   X(6) - std of the normal distribution of S1 samples
% Scatter - the fake scatter corresponding to one Branch and one Segment
% table.
