55f5f8774b ENH: use dictionary findDict() instead of isDict() + subDict()
- avoids redundant dictionary searching

STYLE: remove dictionary lookupOrDefaultCompat wrapper

- deprecated and replaced by getOrDefaultCompat (2019-05).
  The function is usually specific to internal keyword upgrading
  (version compatibility) and unlikely to exist in any user code.

c413ec5009 BUG: writeMorpherCPs expects a controlBoxes entry
The controlBoxes wordList was removed from NURBS3DVolume in the
pre-release phase but writeMorpherCPs was not updated accordingly.

TUT: added the invocation of writeMorpherCPs in one of the tutotials to
help identify future regression

b863254308 ENH: New adjont shape optimisation functionality
The adjoint library is enhanced with new functionality enabling
automated shape optimisation loops.  A parameterisation scheme based on
volumetric B-Splines is introduced, the control points of which act as
the design variables in the optimisation loop [1, 2].  The control
points of the volumetric B-Splines boxes can be defined in either
Cartesian or cylindrical coordinates.

The entire loop (solution of the flow and adjoint equations, computation
of sensitivity derivatives, update of the design variables and mesh) is
run within adjointOptimisationFoam. A number of methods to update the
design variables are implemented, including popular Quasi-Newton methods
like BFGS and methods capable of handling constraints like loop using
the SQP or constraint projection.

The software was developed by PCOpt/NTUA and FOSS GP, with contributions from
