The star class

This class is the main data structure of this package. it represents an initially unclassified YSO to which the standard classification is applied to. To create a new instance of the star class a astropy Table.Row object is used. It holds the photometric data for the given source. The data should consist of spectral flux densities given in Jansky (\([F_\nu] = \mathrm{Jy}\)) and so are the errors (\([\Delta F_\nu] = \mathrm{Jy}\)). To perform the line fitting necessary to determine the spectral index the wavelength at which each flux density measurement is taken is also needed and must be provided in microns (\([\lambda] = \mu\mathrm{m}\)).
