Description

Several files are not conformant with our own style guide.

A quick search shows the following potential violations:

3 File structure, no blank lines at top
./src/Animate.hs
./src/ColorBindings.hs
./src/Colors.hs
./src/Command.hs
./src/Diagnostics.hs
./src/IdentityList.hs
./src/Main.hs
./src/ObjectBehavior.hs
./src/Object.hs
./src/Parser.hs
./src/PhysicalDimensions.hs
./src/RenderLandscape.hs
./src/RenderObject.hs
./src/WorldGeometry.hs

3.3 All Haskell files must include a copyright notice in a comment
src/Animate.hs
src/ColorBindings.hs
src/Colors.hs
src/Command.hs
src/Diagnostics.hs
src/IdentityList.hs
src/Main.hs
src/ObjectBehavior.hs
src/Object.hs
src/Parser.hs
src/PhysicalDimensions.hs
src/RenderLandscape.hs
src/RenderObject.hs
src/WorldGeometry.hs

4.3 The column limit for Haskell files is 80 characters
src/Main.hs
src/Animate.hs

4.5.4.2 No trailing spaces
src/RenderObject.hs
src/WorldGeometry.hs
src/Parser.hs
src/Colors.hs
src/Object.hs

4.7 Comments must always be line comments
./src/RenderObject.hs
./src/WorldGeometry.hs
./src/ColorBindings.hs
./src/PhysicalDimensions.hs
./src/Parser.hs
./src/Colors.hs
./src/ObjectBehavior.hs
./src/Main.hs
