 The morphisms of $A$, from $x$ to $y$, are $\cC(I; x, y)$
 ($\cC$ applied to the standard interval with boundary labeled by $x$ and $y$).
 For simplicity we will now assume there is only one object and suppress it from the notation.
+Henceforth $A$ will also denote its unique morphism space.
 
 A choice of homeomorphism $I\cup I \to I$ induces a chain map $m_2: A\otimes A\to A$.
 We now have two different homeomorphisms $I\cup I\cup I \to I$, but they are isotopic.

 We define a $\Homeo(J)$ action on $\cC(J)$ via $g_*(f, a) = (g\circ f, a)$.
 The $C_*(\Homeo(J))$ action is defined similarly.

+Let $J_1$ and $J_2$ be intervals, and let $J_1\cup J_2$ denote their union along a single boundary point.
