makes sense. a few comments on documentation

[CHrlS98]

A single comment about the doctring. I'll approve anyway.

Tried locally with the fibercup for det/prob and cpu/gpu. Seems consistent. Mean and median length are close.

Stats for prob:

prob_cpu
Num. of fibers: 2321 / 2321
Min. length:    10.0 mm
Max. length:    157.5 mm
Mean length:    81.2 mm
Median length:  79.5 mm
Std. deviation: 44.4 mm
-----------------------------
prob_gpu
Num. of fibers: 2130 / 2130
Min. length:    10.0 mm
Max. length:    158.5 mm
Mean length:    81.1 mm
Median length:  79.5 mm
Std. deviation: 45.2 mm
-----------------------------

Stats for det:

det_cpu
Num. of fibers: 2433 / 2433
Min. length:    10.0 mm
Max. length:    190.5 mm
Mean length:    101.7 mm
Median length:  117.0 mm
Std. deviation: 43.2 mm
-----------------------------
det_gpu
Num. of fibers: 2400 / 2400
Min. length:    10.0 mm
Max. length:    223.5 mm
Mean length:    103.4 mm
Median length:  117.5 mm
Std. deviation: 42.5 mm

we call that a "stream"? Also, the command line argument is only --seed and not --rng_seed so not sure it's clear for the user.

remove linebreak at first line
