[Visual-devel] log_text

[Thomas H. <Tho...@we...>]

I have fixed the code of log_text.cc. I also added log_text2.cc and 
log_text3.cc, which add more features. 

I also added a directory "examples", where I put some test configurations.

These can be started using: 
visual examples/xxx.cfg 2>vout.
