Read a collection of objects, returning true on success.

Object must be considered blittable (see IsBlittable<T>). Note that the storage must have been pre-allocated as it will write directly to the iterators provided. Given that we do not have the STL-style 'back-inserter' classes, for GeoArrays you should use the ReadArray helper function.

There must either be a ReadObject overload for T, or T be considered blittable (see IsBlittable<T>).
