v0.2

• With uneven fit functions (f(r) instead of f(r^2)), the discontinuity at r=0 is solved. Because of this, ring and disc fit functions could be implemented and tested
• Refinement on raw images is best. This allows for more strict test parameters.
• Experimental features added: training of feature shape parameters and per-feature error estimates.
