Stupid files and Python.
Make.py: Added build-dir check.

Added make script and meta file for this project.

Make script now checks if build dir is present and creates it if not.
README.md: Added title,desc and compiling.
gaussiandeviate.cpp: Added premade rand-generator from semester page.
gaussiandeviate.cpp: Cleaned up code.
Particle.hpp,System.hpp: Wrote skeleton.

Copied from FYS3150-Prj03 repo. Modified some names, added some
functions. Need to rethink some more structure. But can keep the main
lines.
meta.dat: Added files.

Added files `gaussiandeviate.cpp`, `SystemLeapFrog.cpp` and
`SystemRK4.cpp`.
System.hpp: Added declaration of RK4 and LeapFrog sub classes.
Added empty implementation of advance method.
Lots of additions and structure.

System.cpp: Copied some code. Wrote full skeleton.
System.hpp: Removed unnecessary fields and methods.
System.cpp: Wrote makeNewParticle() method.
Copied code and started filling in.

Particle.hpp: Removed methods not needed.
Particle.cpp: More or less completed class methods.
System.cpp: Added some includes.
Added type declaration.
System.hpp: Added  declaration in two subclasses. Needed?
System.hpp: Added random generator pointer.
Normal.*: Wrapped gauss rand generator to class.
gaussiandeviate.cpp: Added space.
.gitignore: Ignored build directory.
Many improvements to make script.

Now only compiles files needed to be compiled (object file older than
header or source file itself). This make compilation much faster!

Stores objects files in directory specified via `meta.dat` file. Added
this field to meta file.

Also, slight improvements to printouts and such.
