Julie e18d437924 Making LAPACK's code eternal... no more version and date in source files.
GitHub is now enabling us to track accurately version and date.
No need for this anymore.

Serguei Patchkovskii 9db9ff8556 Updated values of TWOPI and PIOVER2 to 39 significant digits,
to prevent accuracy loss when REAL or DOUBLE PRECISION types
correspond to an extended precision real kind. These constants
should be sufficient to work with 128-bit extended-IEEE data
type.

Rebuilding the modified source using the default gfortran make.inc
(with gfortran 7.5.0) does not add any new test failures. The
only test failure, which is also present in the master baranch, is:

 ZDRGEV3: ZGGEV31 returned INFO=     7.
   N=    12, JTYPE=    16, ISEED=( 2855, 3551, 2406, 2393)

Additionally, included a sample build file for quadruple-precision
compilation using gfortran (version 4.7 or later). With this
config file, both REAL and DOUBLE PRECISION are mapped onto
a 128-bit REAL(16) type, with the corresponding change to the
COMPLEX and COMPLEX*16.

There are numerical failure 6 failures for each type, all in
*GBSVX type 6 matrix, with S/D routines losing 4 significant
digits, and C/Z routines 5 digits relative to the expected
result. I am not really qualified to debug this failure ...

Julie bc6a755be4 Updating version number on source file modified since 3.6.1
This is really old school, but a lot of times we have users sending us
copy pasting of codes, and that is the only way to know the version of
the code.

Hans Johnson 9dafba6d41 STYLE: Remove trailing whitespace in Fortran files
This is mostly a long term maintenance improvement.

Many coding styles require elimination of trailing whitespace, and
many editors and source code management configurations automatically
gobble up whitespace. When these tools gobble up whitespace, it
complicates reviewing the meaningful code changes.

By removing whitespace on one patch, it makes future
code reviews much easier.

julie 1c3ba60067 Cosmetic changes in Doxygen presentation.
Use \par instead of \details for section.

add a Contributors Section and a Reference Section.
Remove (some) verbatim section when not needed.
Those changes have been done by hand so I am not sure I manage to catch them all.
