- avoids compiler ambiguity when virtual methods such as
  IOdictionary::read() exist.

- the method was introduced in 1806, and was thus not yet widely used

- SIGFPE handling, cmake configuration

CONFIG: adjust for simplified Catalyst channel naming

- no sub-channels, select volField output based in the
  (internal | boundary) dictionary switches instead

- improves backward compatibility and more naming consistency.
  Retain setMany(iter1, iter2) to avoid ambiguity with the
  PackedList::set(index, value) method.

- add some notes about 'git submodule' in modules/README.md

- any code placed here should provide Allwmake and Allwclean scripts
  and normally have compilation targets into FOAM_APPBIN, FOAM_LIBBIN

  Since there is no standardize places for sources or applications,
  a simultaneous build of a module's doxygen documentation requires
  a minor bit of manual effort. Add (via symlink) the sources into
  the modules/doc/ directory to have them included in the normal
  OpenFOAM doxygen documentation generation.

  A makelink.example file is provided there as an example.

- disallow insert() of raw pointers, since a failed insertion
  (ie, entry already existed) results in an unmanaged pointer.

  Either insert using an autoPtr, or set() with raw pointers or autoPtr.

- IOobjectList::add() now takes an autoPtr instead of an object reference

- IOobjectList::remove() now returns an autoPtr instead of a raw pointer

- with updated DynList that inherits from UList and uses List/FixedList
  internally for its memory management

- now uses current OpenFOAM code level

- added initial catalyst script for insitu processing of overset

- unify CMakeLists naming and align content

- minor change to pruning of lagrangian fields
