ConnectionBuilder

Demonstrates a method of building sets of connections using a simple set of rules.

The Rules:

1. Every node must have at least connection.
2. All connections must not cross another connection.

Examples:

Index	Left	Right
1	x	x

Should yield (1 set) set: connection (1, 1)

---

Index	Left	Right
1	x	x
2	x

Should yield (1 set) set connection (1, 1) connection (2, 1)

---

Index	Left	Right
1	x	x
2	x	x

Should yield (2 sets), set connection (1, 1) connection (2, 1) set connection (1, 2) connection (2, 2)

---

Index	Left	Right
1	x	x
2	x
3	x	x

Should yield 2 result sets, set connection (1, 1) connection (2, 1) connection (3, 3) set connection (1, 1) connection (2, 3) connection (3, 3)

---

Index	Left	Right
1	x	x
2	x	x
3	x	x

Should yield 2 result sets, set connection (1, 1) connection (2, 2) connection (3, 3) set connection (1, 1) connection (1, 2) connection (2, 2) connection (3, 3) set connection (1, 1) connection (1, 2) connection (2, 2) connection (2, 3) connection (3, 3) set connection (1, 1) connection (1, 2) connection (2, 2) connection (2, 3) connection (3, 3)
