MergeFile.py
"""
Usage:
python MergeFile.py input1.dcm input2.dcm
It will produce a 'merge.dcm' output file, which contains all meta information from input1.dcm
and copy the Stored Pixel values from input2.dcm
This script even works when input2.dcm is a Secondary Capture and does not contains information
such as IOP and IPP...
