A backend update for cucumis !

Yep I had a couple of hours today to work on a few updates mainly for security matters.

Abstract
Background/purpose
In the fabrication of casting post and core or inlay the line angle of the cavity floor can be seen even when the internal axial walls are parallel or slightly convergent. It is conceivable that more sighted distance will be required for internal axial walls evaluation compared with external axial walls evaluation. The aim of the study is to derive a practical and convenient method and data for the evaluation of the divergent angle of internal axial walls.
