gp_shared_buffer example

[ib00]

Is there an example for how to use gp_shared_buffer (OpenCL or CUDA)?

Heya!

Turns out I didn't have any working example using gp_shared_buffers, they should now be fixed for all platforms along with some other stuff so I recommend updating from the main branch.

I added an example in examples/shared_memory about shared memory, covering both gp_shared and gp_shared_buffer.

Great! Thank you!
