3.7.0 (Perfect HELM)

• Replaced the numerical circuit by two specialised objects: one for static power flow and another one for time series, this enhances the speed and improved the maintainability for further functionality such as harmonics of dynamic studies without overcrowding the numerical circuit object with unused stuff.
• Greatly improved the time series flushing speed when saving.
• Improved the auto-link feature in the time series import.
• Added clustering to the time series.
• Added ability to not to draw the schematic. This speeds up operation with very large grids.
• The time series output size now adjust to the selected time interval.
• Now to drop a file does not automatically load the grid when another one is loaded.
• Replaced the previous HELM version by a working and competitive one thanks to Josep Fanals Batllori.
• Added the HELM-Sigma analysis tool.
