Fix relative file paths.

[ghgofort]

As a developer I find there is a much greater likelihood of breaking something inadvertently when using long relative path names with ../../../ to get to the proper directory location. I would expect for these files to be co-located with the other code files that they correspond to (especially tests).

Needed Changes:

• - Co-locate test files with the target file, but inside a tests directory.
• - Create a package.json file for all OCAPI library files (/lib subdirectory).
• - Add the library as a package to the dependencies of the base project.json file.
  -- This will allow for all of the lib files to be included without needing to traverse up the directory tree before specifying the path of a file that is needed.
• - Update all references to the lib files to reference them with the new package notation.

Test files have been re-located so that they live with the files that they are testing.
