MIR Central Test Node DICOM Software Code

Add dcm_strip_odd_groups application.

Add relink target.

Source code for program that strips odd groups from a DICOM file.

Makefile for dcm_strip_odd_groups.

Change the DCM_AddElement to DCM_ModifyElements.
That allows us to add/modify the same element a second time.

Add -T switch to write file in Part 10 format

Add code to sort instance by Image Number if the user configures
the application for that sorting.

Remove spray_image; this belongs in the private_apps.

Add some code to dump and store images, and then comment
out that code. We need to identify the code for that and
add back in later with command line switches to control.

Remove the cstore.o reference
Other changes in link line to get this to link properly.
