Refactor and stand alone examples for KLU class

[shakedregev]

This PR is an enhancement solving Issue 250

kluRefactor.exe and kluStandAlone.exe are now decluttered using ExampleHelper and CliOptions. I kept the two original files, but they are not needed.

Tests pass on CPU.

• [nitpick] Log message refers to 'sysRefactor' instead of 'kluStandAlone'; update the message for consistency with the executable name.

std::cout << "sysRefactor with " << helper.getHardwareBackend() << " backend\n";

The KLU examples are not really decluttered and they do not use ExampleHelper class. Also, CliOptions class should be used to process command line input.

Fixed
