Midas 2025.10.0

Changes have been made to some PES-keywords to make input less verbose in most cases.
See manual for full set of changes.

New Features

The midascpp executable can now dump the contents of /proc/self/maps to stdout using the command-line option --dump-memory-map.
The memory map is dumped at the beginning of the calculation.
Adds an implementation of the Recursive TENsor expansion (RTEN). See manual for details.
The following keywords were added under #1 SinglePoint: #2 IoLevel, #2 DeterminantThr, #2 IgnoreRotation and #2 AllowImproperRotation.
See the manual for details.

Changes

Removed keyword #3 AddFitFuncsConverv and added keyword #3 AddFitFuncsScheme,
which can now be used to toggle between CONSERVATIVE and LEGACY.
CONSERVATIVE is the new default.
Added #3 BasisType under #2 Basis. BSPLINE-basis is now the default. Change basis by setting the #3 BasisType keyword.
Most, if not all, production calculations should use a BSPLINE basis.
#2 DynamicAdgaExt is now on by default. Disable by setting #2 DynamicAdgaExt to FALSE.
PES will now automatically add a single multilevel, if no multilevels are given and only a single SinglePoint is defined.
This will allow users to skip the #2 MultiLevel keyword under PES if only doing a single level.
SP_GENERIC will now automatically chdir to the specific SPC scratch-dir. This means one no longer has to
manually change the directory in the RunScript. The RunScript is still passed the scratch-dir as an argument, meaning that old
RunScripts which did chdir to the scratch-dir should still work as they do now.
Kabsch is now the default option for the keyword #2 RotationScheme under #1 SinglePoint.

Bugfixes

Fixed an issue where only supplying a single integer to #3 AnalyzeStates (i.e. analyze the same number of states for all modes) would make the program crash.
One can now supply a single integer which is then applied to all modes.
Fixed a bug in the LU-based determinant, det(A) = det(PLU).

Let us know if you encounter any problems.
