A simple package that calculates triangle loop using the Feynman approach,

reduced to a single integral.

## Evaluation of amplitude

```julia

triangleloop(m1², m2², m3², M1², M2², M3²)

```

## Position of singularities

```julia

M3² = Polynomial([0im, 1.0])

P = landau_determinant(m1², m2², m3², M1², M2², M3²)

roots(P)

```
