isImage

This function tried to determine whether an object is an image that the
package knows how to handle. If its class is <code>"nifti"</code>,
<code>"niftiImage"</code>, <code>"internalImage"</code> or <code>"MriImage"</code>, then the
result is always <code>TRUE</code>. Likewise if it has an internal image pointer.
If it has no <code>dim</code> attribute, or looks like an affine matrix, then the
result is <code>FALSE</code>. Otherwise the value of the <code>unsure</code> argument
is returned.

Provides an 'R' interface to the 'NiftyReg' image registration tools
<https://github.com/KCL-BMEIS/niftyreg>. Linear and nonlinear registration
are supported, in two and three dimensions.
