Revision history for PDL-IO-Dcm
0.01    2016-12-19
        * First version, already quite mature but needs further testing
0.9	2016-12-20
	* This is a release candidate for v1.0
	
	2017-1-12
	* uploaded this version to PAUSE.
0.9001	* reduced verbose output ( #say ...)
	
	2017-1-13
	* Removed /r switch from regular expressions for backwards compatibility
	
	* better fromatting of list values in text header
0.9002	2017-1-18
	* renamed -n to -i, since there seem complaints about ambiguous options, heh?
	* new switch -p to force split on slice groups, otherwise it tries to force-stack
	  them, if dims allow. Split data sets have empty entries in the respective dimension.
	  Need to find an elegant way to compact data.
	
	* load_dims has now an option reference as second parameter instead of the id-code.
	* new function is_equal 
0.9100	2017-1-19
	* split dims are now compact, no empty entries any more
0.9_200 * PDL::IO::Dcm::Plugin::MRI_Siemens created. Other such plugins can be provided to
	  handle other data. Two functions should be exproted: populate_header and setup
	* printStruct is moved to Dcm.pm
	* default grouping to Dicom series number handled in Dcm.pm, set option
	  id to point to \&sort_series.
0.10	2017-1-20
	* moved more stuff to Plugins, hopefully the interface is clean, now?
	* Created a Plugins/Primitive, sorting simply on instance number. This should
	  be general enough to load any data?
	
	2017-1-23
	* adapted read_dcm.pl to load plugins (-u). Default to Primitive. 
	* check for duplicate entries when loading and parsing dicoms.
1.000	* Version confusion! Best increase major.
	* Writes data using flex raw by default, now. 
	
	* Text header is generated for flexraw and nifit files.
1.001	2017-1-25
	* The header diff element did not contain the reference value, fixed. 
	* added Echo Number, Echo Time, Echo Number(s), Pixel Bandwidth to key_list
	* Integration of PDL::Dims when present and when using PDL::IO::Sereali - started, not used yet. 
	* dcm_key is now Instance Number also for MRISiemens
	
	* the text header now contains the diff field
1.002	2017-2-2
	* Instance number is not always unique, Primitive handles this now by a second (unsorted) index.
1.003	2017-2.8
	* PDL::Dims in MRISiemens support improved, looks good so far, but needs testing.
1.004	2017-2-22
	* Added dcm_key and dim_idx to final stack as hashes
	* PDL::Dims in MRISiemens support improved, especially slice groups, needs testing.
	* Fixing 1-slice only case in init_dims, needs testing.
1.005	2017-50-18 
	
	* Change in handling of poetential duplicates
	* no compact over first 3 indices
1.010	2021-10-21	
	
	* add readme
	
	* adding MRS support
	* split stuff off Dcm.pm into plugins.
	* 0-padding series number in file for easier sorting;
    	* explicit switch for writeflex;
	* less output, progress (.);
    	* skips report files.
	* Slice grops now should work.
	* CSA data support
	* adding sort script. Maybe useful after dicom server zip export.
	* adding sort_dcms.pl to scripts.
	* using Instance UID as unique identifer now.
	* PDL::Dims support
