- Simulation of sequences is now possible by using the 'simulate' option
  on the command line

- Sequences can now be stored as 6 channel AIFF files by using the 'audio'
  command line switch

- The command line switches 'events' and 'tree' for sequences print the
  events along the time axis or the hierachical sequence tree.

- Added variable delay vector SeqDelayVector

- renamed method tj_read_d to odingrech  (basic gradient echo sequence)



Version 0.3.1:
--------------

- New debugging framework. Functions are debugged by generating a local
  Debug object. Additional messages can be emitted by a stream-like syntax.

- The sequence library is distributed over a whole bunch of new files

- The static members systemInfo and geometryInfo are now pointers due to
  problems in initialising the libraries when they are loaded

- Added new program JdxEdit, an interactive editor for JCAMP-DX files


Version 0.3.0:
--------------

- Advanced pulses are now managed by a new class OdinPulse which allows adding new
  pulse shape, trajectory and filter functions via a plug-in style mechanism.

- The Pulsar user interface has been completely rewritten to make use of the OdinPulse class
  and of new mechanism of automatically building a widget from a given JCAMP-DX parameter set.

- Simulation of a sequence is now handled by two classes: SeqDigitised represents the
  digitised RF and gradient waveforms of the sequence and SeqSimMagn holds the magnetisation
  array. Both are then connected by a simulate function.

- The simulation of relaxation effects (T1,T2) were added by Robert Trampel

- The following methods are now part of ODIN:
  -odinmdeft : MDEFT sequence
  -odinonep : onepulse experiment

- IDE for this release was KDevelop 2.1
