Initial solution by raipc

[raipc]

Check List:

• [x] Tests pass (./test.sh <username>)
• [x] All formatting changes by the build are committed
• [x] Output matches that of calculate_average_baseline.sh

• Execution time: 0m11.721s
• Execution time of reference implementation: 4m49.937s

My solution is based on implementing fork/join tasks and using JVM internals to access vectorized intrinsics.

Added custom hash map -- decreased exec time to 0m8.542s

@gunnarmorling I fixed the script and license. Could you merge it, please?

Have some patience, please :) I'm swamped with submissions, and there's an issue with the evaluation environment to sort out. I'll get to this in due course. Thx for hanging in!
