Some questions about Frigate and Semi-Honest-BMR

[Severusted]

Hi Marcella,
Thanks for your work! This project is really amazing!
I'm a new MPC learner. My questions are as follows:

1. I see there are 3 types in Frigate's type system. I'm wondering whether this framework supports floats.
2. After running the mult3 program, I want to ask where is the result. Besides, how to get the random secret key <Key>. Here I didn't set this parameter.
   
3. My inputs are 0010, 1110, and 1111. Does this multiplication circuit really contain 18242 AND gates and 36110 XOR gates?
4. I've learned the paper "Optimizing Semi-Homest Secure Multiparty Computation for the Internet". The document README.txt contains very limited description. It's hard for me to understand and run the code. I would really appreciate it if you could recommend some examples or projects about this implementation.
   BTW, about the version of bison, 2.5.12 wouldn't work and 3.8 could.
   Thanks for your attention!
