Include ReplicateDisplacement and ReplicateImage operations in ANTs's ImageMath interface #3434
Description
Summary
The current version of ANTs's ImageMath interface does not include the operations ReplicateDisplacement and ReplicateImage. These operations can be useful, for instance, to perform a transformation to an 4D image with ANTs's antsApplyTransform (see for instante https://stnava.github.io/fMRIANTs/). Furthermore, there are several other operation of ANTs's ImageMath that could be included without substantially modifying the interface.
Actual behavior
ANTs's ImageMath interface does not include the operations ReplicateDisplacement and ReplicateImage. Many other operations are not included
Expected behavior
ANTs's ImageMath interface includes the operations ReplicateDisplacement and ReplicateImage
