<DL>
<DD>Creates a new sinus factory which creates <code>maxPeaks</code> new
 peaks. Uses Blackman-Harris window function and no spectrum filter as
 default. The adaption type is gaussian with an epsilon of 0.1. The
 factory produces three attributes for each highest peak as default.

<DL>
<DD>Generates a new sinus function attribute for all given attribute peaks.
 Since the frequency cannot be calculated exactly (leakage, aliasing),
 several new attribute may be added for each peak. These additional
 attributes are randomly chosen (uniformly in epsilon range, uniformly
 without nu, gaussian with epsilon as standard deviation)
