Laser-scanning CS.

* Version 1.1

This file lists the changes from the original code of TVAL3 v 1.0.

-----------------------------------------
Modified files
-----------------------------------------

* Remove hard-coded use of cnt and use the global option opts.maxcnt instead
    ftvcs_alp.m and ftvcs_al_TVL2p.m
    
    
-----------------------------------------
Added files
-----------------------------------------

* Adding various new measurement matrices conditions:
    - Fourier ensemble (for comparison in simulations)
        A_fFT.m and At_fFT.m
    - Spatial sub-sampling
        A_sf.m and At_sf.m
    - Spatial with imaging model included
        A_fPsfF.m and At_fPsfD.m

* Prepare an optical transfer function mask based on a small extent PSF
    makeOTF.m

* Extension to 3D for spectral images:
    - Frobenius norm in 3D
        normfro.m
    - 3D directional gradients:
        defDDT3.m
    - 3D solver:
        ftvcs_alp3.m and TVAL3Spectral.m
        
* Pattern creation for use in simulations        
    createPattern.m
    
* Poisson noise generator
    PoissonFct.m
        
* Wrapper functions for simpler use
    ConfocalCS.m and RamanCS.m

* Example script
    exampleSimulated.m, exampleConfocal.m, exampleRaman.m
