Performes peak picking using the CYANA contour line analysis approach

<piktol> specifies the tolerance range (in ppm) for accepting peaks that
are close to the position of the frequency filter can be defined,
e.g. piktol=0.01,0.01,0.1. The order of the tolerances has to
follow the specification in 'format'.

<reference> specifies the axis labels of the frequency filter (peak list),
 i.e. in case of using a 15N-HSQC peak list one has to specify reference=H,N.

<dimension> specifies the axis labels of the spectrum that are equivalent
to the ones specified in 'reference', i.e. in case of using a 15N-HSQC-NOESY
peak list one has to specify dimensions=HN,N, whereas dimensions=N,HN is incorrect.
