v1.0.0 Release Candidate 2

NOTABLE CHANGES:

• multi-event relocation is now performed per cluster: instead of relocating all events in one single double-difference system each cluster is relocated independently. This results in improved solutions since the parameters of the solver are cluster dependent (e.g. downweighting by residuals). Also each cluster covers a smaller area, which helps in avoiding breaking the solver assumption of a flat earth surface (the lat/lon/depth coordinates are converted internally to an euclidean geometry system by the solver)

ENHANCEMENTS:

• changed default configuration values: damping factor enabled by default, meanShiftconstraintWeight disabled. Although those parameters influence each other, the main advantage of damping factor is that it is able to constrain mean shift of the events even when relocating multiple clusters, while meanShiftconstraintWeight works better only when relocating a single cluster
• solver now logs residuals by inter-event distance: this is useful to understand how the relocation is going since the residuals should increase with inter-event distance if the events are correctly relocated (see Waldhauser/Ellsworth)
