The original assignment set forth instructed students to implement a feedforward artificial neural network (ANN) in a relatively low level language or framework. Although higher level scripting languages such as Python and Lua have wrapped heavily optimized libraries that perform the same functions, the goal of this assignment is to truly understand the theoretical underpinnings of feedforward neural networks by writing the routines from scratch (almost).

# The "brute" in brute force
# Question: Given a (large) list of words and a list of top-level domains (TLDs)
# from the Internet Assigned Numbers Authority (IANA), such as ".com" and ".net",
# find all of the possible "singleton" domains that can be registered with words
# from the word list. A singleton domain is defined as a sensical word (ie from
# the word list) whose suffix is a legitimate TLD (ie from the TLD list). You are
# given a function (is_available) that checks whether a given domain name is
