AffineChartGrass -- use an affine chart on the Grassmannian

Description

This is an optional input for methods that involve computations on Grassmannians. The argument l can be a list of $k+1$ distinct integers between 0 and $n$, corresponding to an affine chart $U$ on the Grassmannian $\mathbb{G}(k,n)$. This indicates to the method that should perform internal computations using the chart $U$. Set this to false (resp. true) to not use any chart (resp. to use a random chart).
