<BLOCKQUOTE>
Channel types are given numbers containing the following information:
<UL>
<LI> A numeric index.
<LI> A Number of differentiations 0-2
<LI> 0 for start, 1 for end
</UL>
Things which do not require all these features are packed in according
to the following rules:
<UL>
<LI> Single values which can be differentiated are paired as
if they were start and end positions of an unuknown type
of coefficient.
<LI> Single vaules which can't be differentiated are put in the
positions where the 3rd derivatives would logically be
found.
</UL></BLOCKQUOTE>
