8/// tools::foreach() and tools::transformValues() transform the values in a grid
9/// by iterating over the grid with a user-supplied iterator and applying a
10/// user-supplied functor at each step of the iteration. With tools::foreach(),
11/// the transformation is done in-place on the input grid, whereas with
12/// tools::transformValues(), transformed values are written to an output grid
13/// (which can, for example, have a different value type than the input grid).
14/// Both functions can optionally transform multiple values of the grid in parallel.
15///
16/// tools::accumulate() can be used to accumulate the results of applying a functor
17/// at each step of a grid iteration. (The functor is responsible for storing and
18/// updating intermediate results.) When the iteration is done serially the behavior is
19/// the same as with tools::foreach(), but when multiple values are processed in parallel,
20/// an additional step is performed: when any two threads finish processing,
21/// @c op.join(otherOp) is called on one thread's functor to allow it to coalesce
22/// its intermediate result with the other thread's.
23///
24/// Finally, tools::setValueOnMin(), tools::setValueOnMax(), tools::setValueOnSum()
25/// and tools::setValueOnMult() are wrappers around Tree::modifyValue() (or
26/// ValueAccessor::modifyValue()) for some commmon in-place operations.
27/// These are typically significantly faster than calling getValue() followed by setValue().
