Strings are needed for the handling of identifiers in the key/value
variable storage, so I've got them working first. I used the rope
pattern, which seems to be quite an interesting approach.
I'll add comparison checks later.
Adjusted how buckets are handled in all tests, could've been an issue
down the line.
Added the build instructions to README.md.
At this point, only a minimal number of operations are working, and
after running any kind of source code, the 'result' is simply left on
the VM's stack. Still, it's awesome to see it reach this point.
