Detailed Description

template<typename T, std::size_t NDIM>
class madness::FunctionImpl< T, NDIM >

FunctionImpl holds all Function state to facilitate shallow copy semantics.

Since Function assignment and copy constructors are shallow it greatly simplifies maintaining consistent state to have all (permanent) state encapsulated in a single class. The state is shared between instances using a shared_ptr<FunctionImpl>.

The FunctionImpl inherits all of the functionality of WorldContainer (to store the coefficients) and WorldObject<WorldContainer> (used for RMI and for its unqiue id).

The class methods are public to avoid painful multiple friend template declarations for Function and FunctionImpl ... but this trust should not be abused ... NOTHING except FunctionImpl methods should mess with FunctionImplData. The LB stuff might have to be an exception.

Walk up the tree returning pair(key,node) for first node with coefficients.

Three possibilities.

1) The coeffs are present and returned with the key of the containing node.

2) The coeffs are further up the tree ... the request is forwarded up.

3) The coeffs are futher down the tree ... an empty tensor is returned.

!! This routine is crying out for an optimization to manage the number of messages being sent ... presently each parent is fetched 2^(n*d) times where n is the no. of levels between the level of evaluation and the parent. Alternatively, reimplement multiply as a downward tree walk and just pass the parent down. Slightly less parallelism but much less communication.

double madness::FunctionImpl< T, NDIM >::truncate_tol	(	double	tol,

here is our handwaving argument: this threshold will give each FunctionNode an error of less than tol. The total error can then be as high as sqrt(#nodes) * tol. Therefore in order to account for higher dimensions: divide tol by about the root of number of siblings (2^NDIM) that have a large error when we refine along a deep branch of the tree.
