+Notes:
+- All vars must be included in the class description.
+- All vars have a 'kAnyChIdx' instantiation. The kAnyChIdx variable serves two purposes:
+  + Setting the value of  kAnyChIdx automatically broadcasts the value to all other channels.
+  + kAnyChIdx acts as a template when variables are created by 'channelization'.
+    This allows the network designer to set the value of the kAnyIdx variable
+	and have that become the default value for all subsequent variables
+	which are created without an explicit value.  (Note that his currently
+	works for variables created from within `proc_create()` (i.e.
+	where `sfx_id` == kBaseSfxId, but it doesn't work for mult 
+	variables that are automatically created via `var_register()`
+	because `var_register()` does not have a value to assign to the 
+	kAnyChIdx instance. In this case the variable get assigned
+	the class default value.  The way around this is to explicitely
+	set the mult variable value in the 'in' stmt or the 'args' stmt.)
