#5 fixed LpGlpk::_setColName strange naming bug Balazs Dezso Alpar Juttner

Setting column names of GLPK is not working properly.

void LpGlpk::_setColName(int col, const std::string & name)
{
- lpx_set_col_name(lp,col,const_cast(name.c_str()));
+ lpx_set_col_name(lp,col,const_cast(("["+name+"]").c_str())); 
}
