Code style guide

Accessor naming:

use foo->layer()

instead of

 foo->getLayer();


Exceptions:

Only throw exceptions in rare situations that are effectively unreasonable.

For example:

document->entityByID(...); // return null if a entry does not exists

'Shared pointer passing: never pass shared_ptr by reference

Good:

Line::Line(const geo::Coordinate& start, const geo::Coordinate& end, const shared_ptr<Layer> layer) : CADEntity(layer), Vector(start, end) {..}

Bad:

Line::Line(const geo::Coordinate& start, const geo::Coordinate& end, const shared_ptr<Layer> &layer) : CADEntity(layer), Vector(start, end) {..}
