<DD>
Auxiliary information is used to store information that goes
along with frames, but which are not amplitudes and hence
not appropriate for operations such as interpolation, 
smoothing etc. The aux() array is an array of EST_Vals which 
allows points to be int, float or a string. 

<P>The following functions can be used to access to auxiliary
track information. Most of these functions can be used for
reading or writing to this point, thus

<P>tr.aux(10, "voicing") = 1;

<P>can be used to set the 10th frame of the "voicing" channel and

<P>cout &lt;&lt; tr.a(10, "voicing");

<P>can be used to print the same information. Most of these functions
have a const equivalent for helping the compiler in
read only operations.  

<P>Auxiliary channels are usually accessed by name rather than
numerical index. The names are set using the set_aux_channel_names()
function.
