Is it worth doing indentation in dot files ?
It causes performance issue :
for example, with examples/binary100000.spec settings and seed=4242,
it takes 14 seconds on my machine to generate and export the tree to non-indented dot file, vs. almost 3 minutes with indentation.
should use a faster way to generate the output ... and keep indentations ...
Oops, didn t saw that there is no kind of string buffering... So indentation will be ok !
