Main changes from AIRY 4.0 to AIRY 5.0

1. PEX:
   - Added the possibility to extract PSF when the project runs. This can be 
     done by linking the RFT output to the PEX input. 
   - New Graphical User Interface, based on "tabs". 

2. CNV: 
   - Added the possibility of convolving objects with PSFs "many to many" 
     (It was "one to many").
     
3. ADN:
   - Routine "addnoise.pro" integrated into procedure "adn_add_noise.pro".
   - Output tab added (containing clipping negative values and conversion 
     of the output type). 
   
4. CNV, ADN, PRE:
   - Added possibility to simulate multi-frame images. Multi-frame images 
     cannot be saved (by WFT), but they can automatically reduced by PRE.
 
5. RTI (RoTate Image - new module):
   - The module permits the rotation of an image or a cube. 
     Two different rotations are available: in pixel (using the IDL routine ROT)
     or in frequencies space. 
     N.B.: The rotation can generate artifacts, in particular in the case of 
     point objects/stars. 
     
6. BLI is now CBD (Constrained Blind Deconvolution): the module (previously 
     called BLI) changed its name after the work done for the paper: 
     <<G. Desiderà, M. Carbillet, "Strehl-constrained iterative blind deconvolution 
     for post-adaptive-optics data", 2009, A&A 507, pp. 1759-1762.>>
     
7. ANB: GUI resized, multi-frame case not allowed.

8. DEC: multi-frame case not allowed, image type completed (tag angle added).
     
9. DSP: multi-frame case implemented.

10. FSM: multi-frame case not allowed.

11. OBJ: object type completed (tag angle added), both elliptical disk, 
    gaussian and stellar surface modeling debugged.

12. PRE: 
    - Added DATA REDUCTION for raw images (BAD-PIXEL MAP, FLAT-FIELD MAP,
           DARK CURRENT MAP, and BIAS MAP)
    - Added SHIFT-AND-ADD method. The values of the shift can be either 
           stored in a text file ("x_shift, y_shift" in every line) or computed 
           by correlation (with integer or sub-pixel accuracy)
    - Apodization has been removed (obsolete)
    - Re-centering procedure changed: the new one is based on correlation 
         among the images (with integer or sub-pixel accuracy)
    - New GUI's design with "TABs"

13. RSC: image type completed (tag angle added).

14. WFT: 
    - Multi-frame case implemented. 
    - FITS header completed.
         
15. All modules: 
    - Package version control eliminated.
    - Headers corrected and improved.
