Perform simple peak finder algorithm.

Seeks for gaussians with amplitude more than given threshold (AmplThreshold introduced relative to maximum data value, from 0 to 1), with width in range between MinWidth and MaxWidth. Polynomial approximation can be applied for background approximation(PolOrder >= 0) or not used (PolOrder<0). Only selected by range conditions data part will be used by peak finder. Appropriate number of gaussians will be placed in list of models and associate with data.
