Source work progress
* : $\S 3.3$: Neighborhoods and Neighborhood Spaces: Exercise $3$
 * Got bogged down in Neighborhood Spaces, and I have basically skipped the exercises. Reworking:


 * : Chapter $1$: Theory of Sets: $\S 10$: Arbitrary Products: Exercise $1$
 * Work needed on establishing rigorous definitions and understandable interpretations of a general cartesian product of a family of sets indexed by an uncountable set.

Revisit the following -- it has been glossed over:


 * : Chapter $1$: Theory of Sets: $\S 7$: Relations: Exercise $2$
