directions

+- own project/ repo
+- take rawmodel out of SMNG
+- internal representation of 'stuff' (atoms, coordinates, ...) rather than OST
+  entities
+- start: cases without indels
+- SCRWL for side chains
+- check formats
+- support for oligomers/ ligands
+- don't care about hydrogens for a start
+- deps
+  - OST
+  - BOOST
+  - Eigen (for maths)
+- CMake: Qmean as a template
