Fix for$x^\top (Q + Q^\top) x$ instead of 1/2 $x^\top Q x$ as shown here.
LowerMatrix.dotfunction as it does not give a proper result for QPLIB provided solutions.The way it is handled atm is equivalent to 1/2
Note with this fix,
Problem.evalfunction returns the correct result when QPLIB instances solution is used for x.I have also removed the ".qplib" extension check in file reading, as the qplib format is just a text file and should not be forced to have the qplib extension to be valid, imo.
I thank you for this package and your time
