With exercism/exercism.io@54e1df3, we can now gather exercises into a
subdirectory. By separating the language track files from the
configuration and management files, it is easier to read the project.
- move gradle config under "exercises" too as it would make a mess
otherwise.
- where files are required from the "starter" (./src/main/java), these
are now soft-linked into the example source.
- a couple examples were missing import statements.
- the example code for Hamming was failing the test suite.
At this time, these are all of the problems that have example code.
