Changelog:

• Complete overhaul of the build system: now uses proper CMake target definitions
• Various fixes to ROOT and VTK visualization
• Code cleanup & improved formatting

Kassiopeia:

• Added text file generator (use particle definitions from ASCII file)
• Fixed simulation issues when using "ghost" particle or linear trajectory
• Fixed issue with missing step in output after particle termination
• Restored old ("classic") cosine distribution in generator; added user options: classic vs. molecular

• Fixed issue with reading corrupted files (which led to memory leak)
• Fixed bug in Zonal Harmonic Legendre coefficients (in some rarely used code)
• Fixed bug in electrostatic field map calculation when mirroring is used

KGeoBag:

• Added STL reader with mesh/navigation support; see Kassiopeia example
• Added slice mode for internal VTK viewer (for details open help menu by pressing h)
• Added random generator for annulus surface
• Fixed bugs in extruded spaces (leading to missing / wrongly discretized elements)
• New tool GeometryPrinter to show tree representation of loaded geometry

Kommon:

• Added batch-mode command line flag (-b | -batch); this prevents any visualization windows from opening
• Added TinyExpr formula parser (speeds up parsing of many XML files significantly)
• Fixed log-level command line flags (-v | -q)
