Minor fix to FFT_DEBUG line
(#389)
Get rid of sprintf
(#389)
Clean up some of the residual stuff in the RealGalaxy constructor that isn't needed anymore.

Simplify the logic about pad_image in InterpolatedImage somewhat, and fix some bugs like that pad_image was sometimes overwritten.

Make InterpolatedImage work if pad_image is larger than pad_factor size
(#389)

Conflicts:
	src/SBInterpolatedImage.cpp
Have SBInterpolatedImage sum flux over original bounds rather than odd-sized square.  This allows us to remove an inconsistency in how the pad_image bounds are calculated.  (And simplify this calculation significantly.)

Fix up some post-merge errors
(#432)
Merge branch 'master' into #432
Change the debugging level of some debug statements
(#432)
Add ixrange to Interpolants that return the integer range of the interpolant's extent.  This makes it easier to not worry about rounding issues.
(#432)
Fix the real-space integration ranges for SBInterpolatedImage
(#432)
Avoid slow try/catch block as a control structure in Table::op()
(#432)
Speed up Lanczos xval
(#432)
No need to add split points at the edges.
(#432)
Add unit tests for real-space convolution of SBInterpolatedImage
(#432)
updated CHANGELOG
(#432)
typo
(#432)
explanation in dox regarding real-space convolution for InterpolatedImages, and how to use xValue when using FFT convolution
(#432)
fixed a minor 100char issue
(#432)
a few edits/typo fix on docstring of interpolatedimage.py
