Added function which should give DPI given an image file.
Fully implemented function I found to get DPI. It currently returns infinity.
Transformation added to landmarkWarping2 file. It did actually think it was reading in physical points (by default, an itk::Point is a physical coordinate). We are producing pixel coordinates (itk::Index) in our landmark files. LandmarkWarping now accounts for this and transforms the pixel indices to physical points before doing the warping. Now we can move on to combining the programs into one program that does the entire process.
Removed attempted changes to landmark producing program.
