- HRV power spectrum parameters are now working. Existing problem: Gliding option can have easily too low data points for FFT.

- provided units for result values and added a PSD method (which is still not ready).

- bugfix: Shuffle surrogate option did not work for gliding values in PlotOpComplLogDepth.

- disabled some surrogate methods for HRV analysis because they would produce negative values.

- Bugfix: changed to absolute differences instead of differences including negative values. Computations are now validated by an Excel spreadsheet.

- Values for SDANN and SDNNI should be right now.

- added new plot feature HRV to compute standard HRV parameters (SDANN and SDNNI values are wrong yet!!!!!!)

- changed image file writing from JAI to ImageIO for jpg extension.

- eliminated loci_tools.jar custom import, because it is a very large package and a direct Maven dependency of ome's formats-bsd is enough for J2K reading.

- changed some entries so that mvn verify runs without errors.
