	Resolves issue #1: http://code.google.com/p/virtualleaf/issues/detail?id=1.

	* wallitem.cpp (OnClick): Change dialog modality to Qt::WindowModal.

	Resolves issue #2: http://code.google.com/p/virtualleaf/issues/detail?id=2.

	* canvas.cpp (about): Add link to Plant Physiology paper.

	Resolves issue #3: http://code.google.com/p/virtualleaf/issues/detail?id=3.

2010-11-30    <guravage@petitdru.sen.cwi.nl>

	* canvas.cpp (snapshot): Preface each image format extension with

	an asterisk so files with those extensions to appear in the file

	dialogue.

	(snapshot): Forgot to add asterisk before our own pdf format.

	* VirtualLeaf-install-windows.nsi: Include imageformats folder

	alongside executable.

	* canvas.cpp (snapshot): PNG is the default image format.

2010-11-29    <guravage@petitdru.sen.cwi.nl>

	* canvas.cpp (snapshot): Query and display supported snapshot file

	formats.

	* VirtualLeaf-install-windows.nsi: To facilitate debugging I added

	the debug versions of all the windows DLLs.

2010-10-19    <guravage@caterpie.sen.cwi.nl>

	* mainbase.cpp (Save): Use format specified in function prototype.

	* VirtualLeaf.cpp (Plot): Render PNG instead of JPEG. Write image

	and XML files dependent only on getTime().

2010-10-18    <guravage@caterpie.sen.cwi.nl>

	* mainbase.cpp (Save): QDir::toNativeSeparators(fname). Invoke

	save with format argument set to zero to force QImage to guess the

	format by looking at fileName's suffix.

	* VirtualLeaf-install.nsi: Put uninstaller in top directory.

	* modelcatalogue.cpp (InstallModel): For all OS-es. Move from "bin" directory to root application folder.

	* VirtualLeaf.pro: MAXOSX, look for gpl3.txt in the ../doc directory.

	* Makefile (Makefile.libplugin): Removed -makefile qmake option.

	* VirtualLeaf.cpp (TIMESTEP): Removed getIterations().

	* mesh.h (Mesh): Removed {increment,get}Iterations().

	* canvas.cpp (TimeStepWrap): Replaced getIterations() with getTime().

2010-10-15    <guravage@caterpie.sen.cwi.nl>

	* mesh.h (Mesh): Added iterations. incrementIterations() and

	getIterations().

	* VirtualLeaf.cpp (Plot): Replaced local frame counter with

	mesh.incrementIterations().

	mesh.incrementIterations().

2010-10-14    <guravage@caterpie.sen.cwi.nl>

	* VirtualLeaf.pro: Turned debug off to make all profiles must be

	consistant.

	* VirtualLeaf-install.nsi: Tweaked paths to coincide with UNIX

	distribution, i.e. VirtualLeaf.exe, its libraries, models, and the

	uninstaller all go in the bin directory. And leaves directory

	placed under data directory.

	* canvas.cpp (exportCellData): Added a check to inquire before

	overwritting an existing file.

2010-10-14    <merks@cwi.nl>

	* mesh.cpp: In response to referees' comments, added new parameter

	"yield_threshold" instead of fixed parameter '4' for yield

	threshold.

	* wallitem.cpp: when clicking a wall, both the wall type was

	cycled and the transporterdialog popped up. Corrected this - for

	wall type cycling, hold the Control button while left

	clicking. TransporterDialog only pops up for left click. Also made

	sure the wall is redrawn after changing the transporter values.

	* cell.cpp (DivideWalls): accomodated for rename of Circumference -> WallCircumference

	* hull.h: added an operator< to sort Points

	* hull.cpp: added an operator< to sort Points

	* cellbase.cpp (ExactCircumference): I added a new function

	ExactCircumference, yielding the circumference of the cell along

	its wall_elements

	* VirtualLeaf.cpp: adjust info_string to accomodate for new name

	of function CellBase::Circumference -> CellBase::WallCircumference

	* mesh.cpp: corrected Mesh::Compactness, the boundary coordinates

	need to be sorted in x,y order for the convex hull algorithm

	(thanks Margriet!). I updated CSVExportCellData so it exports the

	circumferences of hull and boundary_polygon.

2010-10-14    <guravage@caterpie.sen.cwi.nl>

	* VirtualLeafpar.tmpl (export_fn_prefix): changed to 'cell.'

2010-10-08    <guravage@caterpie.sen.cwi.nl>

	* pardialog.h:

	* pardialog.cpp:

	* parameter.h:

	* parameter.cpp: Regenerated to include export_interval and export_fn_prefix.

	* VirtualLeafpar.tmpl: Appended export_interval and export_fn_prefix.

	* canvas.h (MainBase): Declared polymorphic exportCellData() functions.

	* canvas.cpp:

	(TimeStamp): New private TimeStamp() function.

	(TimeStepWrap): Added invocation of exportCellData().

	(exportCellData): Created two polymorphic functions: one with a

	single QString argument, the other with no argument. The former is

	called from TimeStepWrap() while the latter is called from the

	"Export cell areas" item in the file menu.

2010-10-07    <guravage@caterpie.sen.cwi.nl>

	* canvas.cpp (exportCellData): Added a Q3FileDialog to inquire

	where to write the exportCellData.

	directory (Linux) or a decedent doc directory (Windows, via the

	binary installer).
