GridArrays defines a collection of basic grids that act as an array. These

arrays are also associated with a domain as defined by [DomainSets.jl](https://github.com/JuliaApproximation/DomainSets.jl).

The package defines the roots of the classical orthogonal polynomials as arrays,

including `ChebyshevTNodes`, `ChebyshevUNodes`, `LegendreNodes` and others.
