Changed 2-yukawa to have better names for the parameters, a macro to plot g(r), and to return S(q)=1000 if the calculation fails, to be more obvious.

Added a Corrlation matrix function (in Wrapper.ipf), but it's not linked anywhere yet, since I don't know yet how best to display it.

Simplified the function to list .ASC files

Added comments to the polarization panel procedures.

     17// -1- Fundamental cell parameters: root:Packages:NIST:Polarization:Cells 
     18//              - default cell parameters are loaded. More cell definitions can be added as more cells are used 
     19//              - changes are saved per experiment 
     20//              - important parameters are held in global key=value strings gCell_<name>  
     21//              - cell names and parameters are used by the 2nd panel for calculation of the Decay constant 
     23// -2- Decay Constant Panel 
     24//              - decay constant determined for each cell. 
     25//              - popping the cell name makes 2 waves, Decay_<cellname> and DecayCalc_<cellname> 
     26//              - Decay_ is the wave presented in the table. Specified transmission run numbers are entered 
     27//                      and "Calc Sel Row" does the calculation of mu and Pcell (for all rows, actually) 
     28//              - DimLabels are used for the arrays to make the column identity more readable than simply an index 
     29//              - time=0 is taken from the first file 
     30//              - Calculations are based on the count rate of the file, corrected for monitor and attenuation 
     31//              - alerts are posted for files in any row that are not at the same attenuation or SDD 
     32//              - if "include" column is == 1, that row will be included in the fit of the decay data 
     33//              - excluded points are plotted in red 
     34//              - results of the fit are printed on the panel, and written to the wave note of the Decay_ wave  
     35//                      (not DecayCalc_) for use in the next panel 
     36//              - manual entry of all of the parameters in the wave note is allowed. 
     39// -3- Flipper Panel (not in this procedure - in Pol_FlipperPanel.ipf) 
     40//              - calculates the flipper and supermirror efficiencies for a given cell AND "condition" 
     41//              - start by entering a condition name and choosing a cell 
     42//              - Waves Cond_<condition>_<cell> and CondCalc_<condition>_<cell> are created 
     43//              - DimLabels are used for the arrays to make the column identity more readable than simply an index 
     44//              - enter transmission run numbers as specified in the table 
     45//              - Do Average will calculate the Psm and PsmPfl values (and errors) and average if more than 
     46//                      one row of data is present (and included) 
     47//              - results are printed on the panel, and written to the wave note of Cond_<condition>_<cell> 
     48//              - results are used in the calculation of the polarization matrix 
     51// -4- PolCor_Panel (not in this procedure - in Pol_PolarizationCorrection.ipf) 
     52//              - gets all of the parameters from the user to do the polariztion correction, then the "normal" SANS reduction 
     53//              - 5 files can be added together for each of the different spin states (more than this??) 
     54//              - global strings in root:Packages:NIST:Polarization:gStr_PolCor_<tab>_<flip>_<position> hold the run number 
     55//              - polarization condition is set with the popup 
     56//              - the same fields/pops are duplicated (hidden) for the SAM/EMP/BGD tabs as needed 
     57//              - on loading of the data, the 2-letter spin state is tagged onto the loaded waves (all of them) 
     58//              - displayed data is simply re-pointed to the desired data 
     59//              - on loading, the raw files are added together as ususal, normalized to monitor counts. Then each contribution  
     60//                      of the file to the polarization matrix is added (scaling each by mon/1e8) 
     61//              - loaded data and PolMatrix are stored in the ususal SAM, EMP, BGD folders. 
     62//              - Polarization correction is done with one click (one per tab). "_pc" tags are added to the resulting names, 
     63//                      and copies of all of the associated waves are again copied (wasteful), but makes switching display very easy 
     64//              - Once all of the polariztion correction is done, then the UU_pc (etc.) data can be reduced as usual (4 passes) 
     65//              - protocol is built as ususal, from this panel only (since the SAM, EMP, and BGD need to be switched, rather than loaded 
     66//              - protocols can be saved/recalled. 
     67//              - reduction will always ask for a protocol rather than using what's on the panel. 
     68//              - closing the panel will save the state (except the protocol). NOT initializing when re-opening will restore the  
     69//                      state of the entered runs and the popups of conditions. 
     79// Panel -1- 
     81// Fundamental He cell parameters. Most of these are pre-defined, so that they are supplied as a
