/**
 * Returns cont(p), i.e. the content of the given polynomial defined as the
 * greatest common divisor of its coefficients.
 *
 * * the sign is chosen such that dividing the polynomial by cont(p) will
 * always result in a positive leading coefficient
 *
 * * see e.g. [Factorization of polynomials](https://en.wikipedia.org/wiki/Factorization_of_polynomials)
 *
 * * example: let `p = -10x² + 5x + 5 = (-5)(2x² - x - 1)` so that `-5` is the
 * content of `p` and `2x² - x - 1` is its primitive part.
 *
 * @param p a polynomial with coefficients given densely as an array of
 * Shewchuk expansions from highest to lowest power, e.g. `[[5],[-3],[0]]`
 * represents the polynomial `5x^2 - 3x`
