Inquiring about an old GSoC

Hello GNU Radio folk,

I have been attempting to use MIMO technology within GNU Radio and have stumbled upon an old Google Summer of Code project sponsored by GNU Radio that does everything I could have wanted to do but in a more competent manner:
https://mimognuradio.wordpress.com/
https://github.com/kit-cel/gnuradio

The commentary by the developer surrounding this suggests that he expected or intended for the final code to be merged into GNU Radio, but it seems like it never was. Is there a reason for this? Is there anything that needs to be changed from the code for it to be merged?

Sincerely,
Chaz M.
