Just a simple application to see how to build something in Crystal.

shards build

This will output an application called students. Run it with:

./students

When you type end it will show the averages per course per student.

The good:

• I am not used to the Ruby/Crystal programming style but I like it so far.
• I like the shards build tool.
• I like the fast compiling.
• Everything is an object.

The bad:

• Documentation is not super. Tutorial is fine but no class documentation (needed to read the code)

The ugly:

• None!
