Detailed Description

template<typename T, size_t NDIM>
class madness::CoeffTracker< T, NDIM >

a class to track where relevant (parent) coeffs are

E.g. if a 6D function is composed of two 3D functions their coefficients must be tracked. We might need coeffs from a box that does not exist, and to avoid searching for parents we track which are their required respective boxes.

CoeffTracker will refer either to a requested key, if it exists, or to its outermost parent.
Children must be made in sequential order to be able to track correctly.

Usage: 1. make the child of a given CoeffTracker. If the parent CoeffTracker refers to a leaf node (flag is_leaf) the child will refer to the same node. Otherwise it will refer to the child node.

retrieve its coefficients (possible communication/ returns a Future). Member variable key always refers to an existing node, so we can fetch it. Once we have the node we can determine if it has children which allows us to make a child (see 1. )
