/* Function.H
 *
 * A function is a mapping from inputs to a boolean output. We read
 * this is from a file. Note the weird syntax "int (*function)(int input[])"
 * refers to a pointer to a C++ function that takes an array of inputs
 * and returns a boolean. This function pointer is called "function"
 * and can be executed by calling "int x = (*function)(inputs);".
