flibs - a collection of Fortran modules SVN

Mostly functional preprocessor. It is not completely general (I have used some shortcuts that rely on my style of programming) and the generated code needs to be correct Fortran, but it is getting in shape.

First implementation of parsing the renaming list

Next step in the preprocessor for templates done. The main task now is to process the list of renames.

Initial checkin: proof of concept for handling templates in Fortran. The file "template_preproc.f90" is meant to preprocess source code that contains definitions or uses of templates (in the way I described in a note). The file "def_collection_file.f90" is an example from my other note - "Experimenting with generic programming features".

Commit a collection of files that demonstrate some possibilities to generic programming

Add a new check - some compilers allow writing derived types with allocatable components via list-directed output as an extension.

Update the generated HTML pages and add the documentation of the string_operations module.

Add the "read_line_from_file" subroutine - a more modern version of the corresponding routine in the singleline_text module - and easier to use. It relies on allocatable-length strings, as do the other routines in the string_operations module.

Add test case for the "read_line_from_file" subroutine

Add test program for the string operations module
