[Dcmlib] exCurveData

[Mathieu Malaterre]

Hello there,

	I recently commited a small example to explore the 'Curve Data' 
(50xx,3000) and co. tags. This has only been tested on 
GE_DLX-8-MONO2-Multiframe.dcm since this was the only available DICOM 
with this tag I had.

Basically it dumps/interpret the following tags:
/*
  * V 5004|0000 [UL]                  [Group Length] [1998] x(7ce)
  * V 5004|0005 [US]              [Curve Dimensions] [1] x(1)
  * V 5004|0010 [US]              [Number of Points] [969] x(3c9)
  * V 5004|0020 [CS]                  [Type of Data] [PHYSIO]
  * V 5004|0022 [LO]             [Curve Description] []
  * V 5004|0103 [US]     [Data Value Representation] [0] x(0)
  * B 5004|3000 [OW]                    [Curve Data] [gdcm::Binary data 
loaded;length = 1938]
  */

Comments welcome
