Put the ftn95p project file into the repo.
Got a pair of fortran & c# process that

* C# can read from fortran
* C# doesn't hang until fortran finishes.
This is messy--just committing in case I f*** it up later.
Working version

* Two-way communication via stdin / stdout
* Basic handshaking system
* Console only
* Disabled the second blank Console window for the F95 process
