Intrinsic Alignment and Fisher Matrix

Added the intrinsic alignment, as modeled in the Euclid IST:F paper.
The Fisher matrix evaluation has been tested against SEYFERT.

Beyond Limber

This the first tagged version with a working Beyond Limber approximation. This is not meant to be a production-ready release, since there are still a couple of minor things to be addressed.

Euclid Bias

In this release we have added the Euclid Flagship bias, according to this paper.. This is not a production ready release, we need to perform further tests before merging on the master branch.

Simpson Integration

The Simpson Integration has been implemented. All integrals are accelerated using LoopVectorization.jl to enhance performance.

Derivatives wrt Cosmological parameters

The derivative of Angular Coefficients wrt to Cosmological parmeters has been added.
The accuracy of the implementation has been tested against Seyfert, reaching a PAD of about 10^-3 in derivatives

First release

In this release, Angular coefficients for a w0wacdm cosmology are evaluated for the following probes

1. Galaxy Clustering
2. Weak Lensing
