BUG: The padded z bounds were not getting intialized and on some compilers this was causing problems.
ENH: The layout now defaults to 200 iterations instead of 100
ENH: The gaussian fallout is now e-10 instead of e-20

BUG: 5445: restored necessary warning suppression for MS compiler, made the CMakeLists.txt better match the ITK version

ENH: Adding vtkAppendSeleciton and vtkSelectionLink, along with a test for vtkAppendSelection.

ENH: Make extractselection produce a second output, which holds an ids selection that helps to correlate entries in the output data set to the input data set.

ENH: Allow fetch to use different reduction algorithms for each composite data type. This way multiblock data appears as multiblock data on the client.

STYLE: fix typo

BUG: An update progress was send every time a cell center was computed, which could really slow down the process if that actually updates a GUI.  Now only send an update every 1000th cell center computation.

BUG: 5445: tweaks on 1.2.3 upgrade: the minimal set of warnings for bcc was determined and is now in place, MS Visual Studio warning suppression removed to see which are actually still needed in 1.2.3

ENH: Methods to initialize a contour widget from user defined geometry. Also set the interaction state appropriately.

BUG: 5445: tweaks on 1.2.3 upgrade: cosmetic changes to keep itk and vtk zlibs as close as possible, suppress more compiler warnings, updated readme, added HAVE_UNISTD_H test, removed some warning suppression to see if the new zlib fixed them

BUG: fixing uninitialized memory access; set numTypes to the number of entries in the type array; add VTK_STRING to the type array

ENH: Modified code to set ContentType in IDs selection case for emplty selection, so that extract selection filter will pass the content type checking.

BUG: make the string static, otherwise the contents are gone when we exit the functions
