Moved the file/unit check for a JSON file when writing to its own subroutine.  However, based on issues observed with Intel 18.0.2, I've commented it out.  (This was present in the original inlined version too.)

Added module procedure to convert values into the associated JSON formatted string, rather than doing it explicitly for each value and name/value writing.

Tweaked Doxyfile to my liking (and renamed it from doxyfile).  Added code fragments to README.md file; want to see how they render on GitHub.

All output is now routed through the fjson_write subroutine.  Added error checking for the file not being open to writing.

CTest now uses a script (which I shamelessly stole from the CMake mailing list) to compare the output of a test executable against a known-good/blessed output.

Added positive unit tests.  Currently, they are always built, and no testing is done to determine if the resulting JSON actually is valid.

Changed some variable names which were holdovers from ELSI.  Properly capitalized FortJSON throughout code.

Added an error case for the handle being uninitialized.  If it is, the code will not output anything to it.

Modified error handling.  Code will no longer stop abruptly, instead it will output an error message to the JSON text (breaking the parsing) and set a dirty error bit, which is user-accessible via two functions.  This allows users to determine how they want to handle errors, and it also allows them to modify the JSON by hand if the error was isolated and not overly dramatic (say, outputting a name/value pair instead of a value).

Turns out that ECMA-404 DOES support an individual value as a JSON text.  Created a test subdirectory to store testing programs and moved my test program tehre.

Added README file in Markdown.  Removed requirement inherited from ELSI that user manually specify the Fortran compiler.

Added doxygen commenting to code.  Needs to be added to cmake build system (as an optional feature).

Since this code is no longer a subset of ELSI, modified the style to better suite my aethestics.  Removed two legacy variables.

Added objects and arrays as values for name/value pairs.  The main pieces for JSON output are now implemented; from here on, it's code cleanup, filling in additional value, more error handling, and testing.
