CHANGES in 1.5

1. Standardized reflectivity library, making it mush simpler to deal with reflectivity files
2. The shipped MCPL-library has been updated
3. Updated and streamlines the installation procedure - such that windows and Mac installs are now (almost completely sandboxed).
4. New components:
        1. Bragg_crystal (replacing Perfect_crystal)
        2. Bragg_crystal_BC
        3. Laue_crystal_BC
        4. Reflective grating
        5. SAXS_samples series
        6. Attenuating_mask
        7. Phi_monitor: Phase monitor.
5. Updates to components:
        1. Mirror comp - can now be either in the xz or yz-plane
        2. Virtual option to Mask-component - used to artifically add a 2D-pattern to a subsequent component.
        3. Mirrors now use the refletivity library
        4. Source_lab: Add Ag as an anode material
        5. Source_lab: Default is now to use lorentzian line-shapes
        6. Undulator: Easier to compile with GSL on windows
        7. PowderN Major improvement in the way incoherent scattering is handled
        8. Monitors: Monitors now have a nowritefile option to dynamically disable monitor (useful if an instrument has a lot of monitors)
        9. PSD_monitor: pixel count can now be set by a variable
        10. PSD_monitor_coh: optionally rays are now treated as if they hit a pixel center. This avoids convoluting the pixel shape in the interference pattern
        11. MCPL: encode polarization vector 
6. several new example and updated instruments:
        1. MAXIV_Bloch
        2. MAXIV_DanMax
        3. DBD_IBM_Si_analyzer
        4. PDB_BT
        5. Template_Johann_spectrometer
        6. Updated Test instruments (many of these can be used as examples)
7. Updates to the GUI - including autoplot options and imporved stability of the plotting and disply subsystems
8. Performance improvement to MPI
9. Better performance on reading datafiles (especially on windows)
10. Updated manual
... and more

CHANGES in 1.4

1. Source_pt, Source_flat, Source_gaussian, and Source_div now behave in the same manner wrt. phase. The relevant parameters
are randomphase and phase. If randomphase is !=0 the phase is completely random, if ==0 the value of phase is used.
2. EPSD_monitor: Has a parameter nE which denotes a number of energy bins. if >1 the monitor will output a number of files
each corresponding to an energy bin.
3. Lens_parab, Lens_parab_Cyl The functionality of the _rough versions of these components have been merged into the main components
and the _rough versions themselves retired.
4. Support for binary file dump of photons in the mcpl-format is added.
5. On debian class systems, McXtrace now installs to /usr/share to be more standards compliant.
6. New Components:
    sources/Undulator.comp: Undulator model based on Kim, 1989, “Characteristics of synchrotron radiation”
    
    samples/Incoherent.comp: Model sample of an incoherent scatterer
    samples/Polycrystal.comp: Polycrystal sample based on Single_crystal formalism
    samples/SasView_model.comp: All samples included in the SasModels module of SasView.
    	Currently does not take in absorption into account
    
    misc/Air.comp: A “box” full of Air that may scatter-
    misc/Focus.comp: Adds resampling to any component. I.e. causes the preceding object to become a secondary source.
    misc/MCPL_input.comp: Interface components to read/write MCPL-format files. 
    misc/MCPL_output.comp

    monitors/DivE_monitor.comp
    monitors/DivPos_monitor.comp
    monitors/Divergence_monitor.comp

    optics/Bragg_crystal.comp: Superseeds Perfect_Crystal
    optics/Bragg_crystal_bent.comp: Bent crystal model
    optics/Capillary.comp: Capillary tube with reflecting walls.
 
    optics/Collimator_linear.comp: Ideal collimator models
    optics/Collimator_radial.comp
    optics/Mirror.comp: Simple flat mirror component
    optics/Mirror_toroid.comp: Toroidal mirror
 
    contrib/Detector_pn.comp: Detector model with quantum efficiency.
    contrib/SAXS/SAXSCurve.comp: A set of SAXS-sample models
    contrib/SAXS/SAXSCylinders.comp
    contrib/SAXS/SAXSEllipticCylinders.comp
    contrib/SAXS/SAXSLiposomes.comp
    contrib/SAXS/SAXSNanodiscsFast.comp
    contrib/SAXS/SAXSNanodiscsWithTagsFast.comp
    contrib/SAXS/SAXSNanodiscsWithTags.comp
    contrib/SAXS/SAXSNanodiscs.comp
    contrib/SAXS/SAXSPDBFast.comp

    contrib/SAXS/SAXSSpheres.comp

7. Example Instrument simulations:

  - Pump_probe_solvent: Example of disordered scattering in solution
  - SAXS_saxlab: Laboratory SAXS setup with Montel optic
  - template_1Slit_Diff & template_2Slit_Diff: examples of raytracing with coherent interference effects.
  - ESRF_ID01: Microdiffraction beamline with polycrystal sample
  - templateSasView: Example of using the (experimental) SasView interface 
  ... and various Unit test/Example instruments

8. New python/Qt based GUI/plotting tool
