When using 'simple' or 'hierarchical' decomposition it is useful to slightly rotate a coordinate-aligned block-mesh to improve the processor boundaries by avoiding irregular cell distribution at those boundaries. The degree of slight rotation is controlled by the 'delta' coefficient and a value of 0.001 is generally suitable so to avoid unnecessary clutter in 'decomposeParDict' 'delta' now defaults to this value.
Test application for volField and surfaceField mapping with

block/Allrun
to compile and map a few fields. Note that hexRef8 cannot be
run in inflation mode - there is the problem of getting
a set of faces to sweep that is consistent for a cell and
all its neighbours.
