Fixes for the c++ Simple and Extended examples in readme

[unexploredtest]

There were some missed semi-colons and >s which prevented the Simple and Extended examples from compiling; also, the code was trying to print std::vector which is not feasible. I could run the first one successfully, but the Extended example(second one) though compiles successfully, crashes my system when trying to execute sq->eval(); , so I'm not sure. Hope this fix is useful, as I'm still trying to learn this library.

Good catch @aliPMPAINT ! Thank you for the contribution!

[unexploredtest]

Thanks!
One last note @axsaucedo , kp::Manager mgr(0, { 2 }); with family index of 2 caused my system to freeze(and then I have to restart it), family index 1 and 0 worked fine.

@aliPMPAINT you are totally right, I also experienced this actually when putting together this blog post, I was going to raise it as an issue but I wasn't really sure where would be the best place to raise this, as ultimately it does seem to be a Vulkan issue - namely it shouldn't really crash your entire computer when a queue is added when it doesn't exist.

Given this has come up again it may be worth opening an issue in one of the Vulkan official repos

@axsaucedo , gotcha, which repository is appropriate?
And on the mean time, is it better to change the family index to 1 or 0?

[axsaucedo]

You actually have to check which family indices are supported based on your graphics card, for example in my nvidia card I can use index 0 and 2 for compute and 1 for transfer http://vulkan.gpuinfo.org/displayreport.php?id=9700#queuefamilies. The blog post covers this in a bit more detail, but let me know if you have questions regarrding of why this is the case

[unexploredtest]

Oh, got it. Sorry for my silly misconception.

No worries @aliPMPAINT definitely not a simple one, it took me a long time and a lot of asking to figure out the nuances with familyQueues and GPU queues, so definitely good questions
