adding & subtracting multiple points after calling ``build()``

[jGaboardi]

Currently with FastPair.__add__() only a single point can be added at time after calling build():

def __add__(self, p):
    self.points.append(p)
    if self.initialized:
        self._find_neighbor(p)
    elif len(self) >= self.min_points:
        self.build()
    return self

With some modification, a collection of points could be added to the data structure:

def __add__(self, p):
    if isinstance(p, list):
        for _p in p:
            self._add_1_point(_p)
    else:
        self._add_1_point(p)
    return self

def _add_1_point(self, p):
    self.points.append(p)
    if self.initialized:
        self._find_neighbor(p)
    elif len(self) >= self.min_points:
        self.build()
    return self

Seems like the same could go for FastPair.__sub__()

Thoughts?

Nice catch!

If we pass other types like geoSeries or np.array? Assuming that we will only support list, it is up to the user to pass the argument correctly. I mean, if the user has a geoSeries, it has to convert geoSeries to list.

I think we should support at least np.array, to provide a "medium-level" API. What are your thoughts?

I agree, and this would probably play nicely with numba & jit decorators for improved performance (in the future, of course).
