 AVW_VIEW: Create and navigate ortho views of Analyze file

 avw_view(avw)

 avw    -  a struct, created by avw_img_read

 The navigation is by sliders and mouse clicks on the
 images in any of the ortho views.
 Fiducial points can be selected, which are returned
 into mriFID or p.mriFID in the base workspace.  These
 points are given in meters, with an origin translated 
 from the center of the MRI volume to (0,0,0).  +X is
 right, +Y is anterior, +Z is superior, the default RAS
 orientation of Analyze MRI files.
