cfac-1.7.0

This is a major release. Please note that it introduces a few backward-incompatible changes.

• Level names are now guaranteed to be unique within the same ion; a repeating (in the previous versions) name will now have one or more asterisks appended.
• CorrectEnergy() now expects a file with levels identified by their names instead of indices.
• By the end of calculations, a warning is issued if not all energy corrections have been applied.
• Improved calculations of CE between nearly degenerate levels.
• Atomic constants updated to their current CODATA values.
• The obsolete form of Structure() is dropped.
• Removed non-functional SetTransitionMaxE/M() calls.
• Removed SetModName().
• Added SetErrorOutput() function to redirect the error/warning messages to a file.
• By default, the output is set to stderr. Use SetErrorOutput('stdout') to restore the old behavior.
• Mixed calculation mode is no longer marked as experimental.
• Config() now accepts the uta flag.
• SetUTA() is marked as deprecated.
• Added convenience OptimizePotential() call combining ConfigEnergy(0), OptimizeRadial(), and ConfigEnergy(1).
• Added RequireVersion().
• Alternative "per-ion" forms of several functions are documented.
• The SQLite DB now includes the uta flag per level; format version changed to 4, one needs to recompile any code against the updated cfacdb library.
• The cfacdbu utility can detect whether (a subset of) a DB was prepared in the detailed, UTA, or mixed mode.
• Fixed printing stats of multisession DB's.
• Various cosmetic fixes and documentation updates.
