/** For exocytosis from an intracellular to a membrane-bound Node. Use this one in the Node
representing the membrane-bound (or extracellular) compartment. Each face of the cell gets 1/num_sides
of the exocytosed material. Note that a separate Node is used for the
intracellular and the extracellular protein pools, even though the protein 
itself may be identical in both locations.

<p> <b>Formula</b>
<br>dE_NODEX/dt = exo_NODEX * I_NODEX / num_sides_per_cell

<p> <b>Parameters</b>
<table width="500" border="1">
<tr><td width="150">Intracellular Node [I_NODEX]</td><td> The intracellular Node that is being exocytosed</td></tr>
<tr><td width="150">Extracellular Node [E_NODEX]</td><td> The extracellular Node representing the now membrane-bound protein</td></tr>
<tr><td>Exocytosis rate [exo_NODEX]</td><td> The rate at which Node is exocytosed.</td></tr>
</table>

<p> <b>Usage</b>
<code><font size = "3"><br>&E_NODEX
<blockquote>    &ExoEAff  I_NODEX  E_NODEX	exo_NODEX
