is_feasible_point will determine if a given point is in the interior of the intersection of one or more fully specified ellipes.

1	is_feasible_point(point, ell)

`point`	a numeric of length equal to the dimensions of the ellipses in `ell`.
`ell`	a list of at least one ellipse; see `wrangle_ellipse`.

Given a point is_feasible_point will check if this point is in the intersection of the list of ellipses ell. Note that this function will not check if the intersection is non-empty.

is_feasible_point returns an object of class "is_feasible_point". This object is a list containing the following components:

`point`	the inputted `point`.
`fasible`	logical; is `TRUE` when the point `x` is in the interior of all ellipses.
`distance`	a data.frame with the distance from `x` to the center of each ellipse, the radius of each ellipse and a logical indicator, which is `TRUE` when `x` is an element in the ellipse.
`call`	the match call.

wrangle_ellipse for detailed on ellipse parameterization.
