DEBUG. Increased build warning level to \W4. Added some missing linefeeds to new DEB_out streaming. Raised level of TRACE_GUROBI_INPUT deb out to 7 and decerased default DEB_out level to 5 so as to redisable this output by default.
 No behaviour changes anticipated other than changed DEB_out content.
