For higher-dimensional polynomials, the fitting data structure for each level would be a `numpy.array` of shape `(n, n, ...)`, but only the lower (or upper) triangle of `(n,n)` is used....

[The Clenshaw algorithm](https://en.wikipedia.org/wiki/Clenshaw_algorithm) allows the efficient computation of linear combination of recurrence-scheme polynomials. It'd be nice if this could be extended to all of the polynomials classes in orthopy. (Suggestion...

Note sure if the BigQuery API allows this, but I'd like to have download stats per pypi, user, not per project.
