[glamperd]

Example:

phase1_prepare_phase2 challenge_0006.response 10 512
Creating phase1radix2m0
Creating phase1radix2m1
Creating phase1radix2m2
Creating phase1radix2m3
Creating phase1radix2m4
Creating phase1radix2m5
Creating phase1radix2m6
Creating phase1radix2m7
Creating phase1radix2m8
Creating phase1radix2m9
Creating phase1radix2m10

Then choose the phase1radix2 file to match your circuit size, and run phase2_new to start the phase 2 setup.
