Tess

===================
* Fixed typo in random_points.cc example. Thanks to Guo-Jie Gao (Osaka
University) and Jose Adsuara (Universit of Valencia) for pointing this out.
* Fixed documentation error in normals routine. Thanks to Jean Farago
(Université de Strasbourg) for pointing this out.

=================================
* Fixed an issue with template instantiation in wall.cc that was causing
compilation problems with new versions of Apple Xcode. Thanks to Barend
Thijsse (Delft University of Technology) and Juan Pablo Cruz Pérez (Instituto
de Física y Matemáticas) for pointing this out.
* Added routines to the container classes to compute a ghost Voronoi cell at
any given location, as though an extra particle was inserted at that
location
* Removed unused private variable in c_loops.hh
* Updated Doxyfile to 1.8.5

==============================
* Removed "using namespace std" from the header files and added extra "std::"
qualifiers on STL vectors and queues. This is to prevent naming conflicts
with other libraries. Thanks to Florian Hoffmann (University of Luxembourg)
for pointing this out.
* Fixed an error in the check_facets diagnostic routine. Thanks to Tristan
Carrier-Baudouin (Université catholique de Louvain) for pointing this out.
* Fixed a memory leak in the new container_periodic class. Thanks to Massimo
Marchi (Commissariat á l'Energie Atomique) for pointing this out.
* Removed some duplicate or unnecessary include statements of the standard C++
header files
* Fix small naming mismatch between cell.cc and cell.hh in plane_intersects
and nplane routines, which would give a warning with Doxygen
* More changes for older MS Visual C++ compatability
* Updated Doxyfile to 1.8.1.1

=================================
* Fixed an error in pointer arithmetic that was introduced in version 0.4,
which would occur in cases where the delete stack was extended when a large
number of vertices were being removed. Thanks to Jeff Johnson (Lawrence
Berkeley Laboratory) and Matt Freeman (Texas A&M University) for pointing
this out.

==================================
* Removed spurious Gnuplot output line from torus.cc example
* More changes for better Visual C++ compatibility
* Fixed indexing error in worklist generation routine. This had no effect
on the generated worklists, but would become apparent in other situations.
* Added rad_option.hh to the list of files included by voro++.hh for
completeness
* Fix errors in Gnuplot commands in the basic examples README file. Thanks to
William-Fernando Oquendo (National University of Colombia) for pointing this
out.
* Fixed memory allocation issue in face_freq_table routine - thanks to Lingti
Kong for pointing this out
* Minor cleanups and optimizations to wall classes

===================================
* Fixed a bug in the put_remap routine where a z periodic boolean was
switched to an x periodic boolean. This would only be noticed when using
mixed periodic boundary conditions and importing particles that need to be
remapped.
* The pid function in the c_loop_base class was mistakenly labeled as double
instead of int - this is now fixed. Thanks to William-Fernando Oquendo
(National University of Colombia) for pointing this out.
* Fixed an extremely subtle bounds checking issue that would only materialize
for the radical Voronoi tessellation with large particle radii. Thanks to
Richard Martin and Maciej Haranczyk (Lawrence Berkeley Laboratory) for
pointing out the original problem.
* Fixed other problems with the radical tessellation. Originally, the
algorithms were concieved for with hard spheres in mind, where the particles
would not overlap, and an assumption was used in the cutoff procedure that
made use of this, but would not be true in general.
* Removed more bracket initializations like "double a(3);" for better
consistency, and more compatibility with older versions of MS Visual C++.
Thanks to Martin Brehm for help with this.
* Factored out the regular/radical inline routines into separate classes, so
that they don't have to be duplicated in the container_periodic classes
* Fixed problems with the container_periodic classes referencing the wrong
loop classes. Thanks to Wang Chuncheng (Nanyang Technological University) for
pointing this out.
* Added c_loop_order_periodic class for doing ordered loops with the periodic
container classes
* Updated the README file in the src directory. The detailed description of
each file has been removed since this is difficult to maintain and this
information is already present in the class reference manual.
* Fixed an error in the pre_container selection of the optimal computational
grid size
* Code comment cleanups, particularly in wall.hh
* Minor man page reformatting
* Updated Doxyfile to version 1.7.5.1
