The bit_random mutator introduces random variation by first
converting a randomly chosen variable of a randomly chosen design into
a binary string. It then flips a randomly chosen bit in the string
from a 1 to a 0 or visa versa. In this mutation scheme, the resulting
value has more probability of being similar to the original value.
