adding Benni's notes

README.md

+# A Prototype Game for [UFrameIT](https://uframeit.github.io)
+
+This Math Archive contains three directories:
+
+## Library:
+All things to describe basic math things.
+
+Currently in use are:
+  - `3DVector.mmt`
+  - `Lines.mmt`
+
+Most of the other stuff was practicing MMT / having fun with it.
+*Note*: `BenniDoesStuff.mmt` collects all theories of this folder and is used as some kind of basic geometry-language.
+
+## Fact-Types:
+`FactTypes.mmt`: Definition of the FrameIt-Fact-Types:
+ - Distance, Angles, OnLine
+ - The "UnorderedPair" was a experiment to solve the `Type( d(a,b) ) == Type( d(b,a) )`  problem.
+	Which should be solved by the equality-rule from Dennis right now
+- Note that `Vector` and `Line` use the "constructor"-functions from 3DVector.mmt and Line.mmt of the library-directory
+
+`FactCollection.mmt`: Collects all FactType-theories to act as a language to implement scrolls
+
+## Scrolls:
+`ScrollMeta.mmt`:
+ - Some declarations to act as meta-keys at the scroll-formalizations
+
+other files:
+ - Scrolls as Problem-Solution Pairs
+ - Usable at the time of my submission
+ - All but the TangensScroll strangly dissapeared on the 	 playable Demo =(
+ - `PlaygroundScroll.mmt`: playground to test views,   Communication	with the frontend etc.
