Search the mesh for an element located at coordinates (x, y, z). This is a sometimes useful but inefficient way of accessing elements, as it relies on a search in a spatial octree. If an element is found, return its tag, type and node tags, as well as the local coordinates (u, v, w) within the element corresponding to search location. If dim is >= 0, only search for elements of the given dimension. If strict is not set, use a tolerance to find elements near the search location.
