[spp] python2 support

[Yasufumi Ogawa]

Hi Ferruh,

You are required to install 'future' module by running 'pip install 
future' for using 'queue' with both of Python 2 and 3. I should include 
this instruction in SPP documentation.

I think I should add 'requirements.txt' to install all of required 
modules and not disturb users. I would like to send a patch for updating.

Thanks,
Yasufumi
