[Blackmax] Print BH to LHA_Output

[Eram Rizvi]

Hi Michiru,

Yes, that is correct - you can add the BH to the output in that way,
unfortunately this is likely to cause problems with the hadronisation
step and the lines of colour flow, but if you're only interested in
the evolution of the BH as it decays then you can use the method you
described. Of course, more complete information about the BH is given
in the output.txt file including it's location on the brane after each
emission step as well as its complete n-dimensional momentum.

I hope that helps.

Cheers
Eram
