  1. I worked on Light Nuclei Density Distribution models. I added 3pF(fer…

    …mi) model , Harmonic Oscillator Model, Sum of Gaussian model and also updated the Radius parameter used in the Gaussian Density Distribution model to measured RMS radius.
    
    I changed the nEgamma from 1000 to 100 & nQ2 from 1000 to 100 to speed up cross section calculation in e_wideResonanceCrossSection::crossSectionCalculation function and also added percentage progress code and fixed wideResonanceCrossSection calculation by calling photonNucleusCrossSection::e_getcsgA function instead of photonNucleusCrossSection::getcsgA function.
    I implemented four prong channel.
    I changed the data for gauss integration from NGAUSS = 6 to NGAUSS = 16 in photonNucleusCrossSection::e_getcsgA to improve precision.

    I updated nuclear density distribution models for some light nuclei. I worked on H-2, He-4, Be-10, B-11, C-12, N-14, O-16. I added three parameter Fermi model for  N-14 & O-16 and the sum-of-Gaussian model for He-4 & C-12 and updated the default radius to the measured rms radius for the remaining nuclei following the Gaussian model (H-2, Be-10, and B-11 ). Also, I added the form factor for the sum-of-Gaussian model.
