treeplot function

[matbesancon]

function treeplot(trr::Tree, fig= 1)
    if !isempty(fig)
        figure(fig)
    end
    # ...

it is not trivial what exactly users should pass as fig argument. isempty for a number is always false. What else could they pass to have it empty? In that case what happens?

Sometimes, a user may want to have his/her picture larger than what the package returns. In this case, having fig = (8,6) for example will increase the size of the image. That is why we have that optional argument.

ok I see, this should be documented in the docstring of the function

I will add it in the docstrings as I update the stable package version.

@matbesancon It is done. I have also updated all the stable documentation in the README and the paper. As well I have bumped up the version to v0.20.
