Small component selection for cleaning scan data or getting rid of tiny shells

[Ellie123]

Sometimes scan data is full of little tiny bits of mesh that need deleting- easily filtered in Mesh lab. Would be nice similar feature in

3dc.

But I also noticed that when using certain tools like Carve in Voxel room tiny shells can be created (invisible to the

eye). So sometimes one can be creating these shells unknowingly. 

Love 3dc for 3d print prep would like to see few more tools to help with this workflow
