* Points: translate doxygen from DE to EN + fix superfluous whitespace
For the purpose of making the source documentation uniform, source comments in this file were translated to english.

* Fix left over DE to EN translations (from Cam and Mesh code)
+ some are doxy others are just comment code.
+ some minor whitespace and grammatical tweaks.
+ app/SCL/* typos have also been submitted upstream (https://github.com/stepcode/stepcode/pull/366). So it's ok to merge them in to master.
