Within decomposeParDict, it is now possible to specify a different
decomposition method, methods coefficients or number of subdomains
for each region individually.
The top-level numberOfSubdomains remains mandatory, since this
specifies the number of domains for the entire simulation.
The individual regions may use the same number or fewer domains.
Any optional method coefficients can be specified in a general
"coeffs" entry or a method-specific one, eg "metisCoeffs".
For multiLevel, only the method-specific "multiLevelCoeffs" dictionary
is used, and is also mandatory.

ENH: shortcut specification for multiLevel.
In addition to the longer dictionary form, it is also possible to
use a shorter notation for multiLevel decomposition when the same
decomposition method applies to each level.
The combined solver includes the most advanced and general functionality from
each solver including:
Continuous phase
Lagrangian multiphase parcels
Optional film
Continuous and Lagrangian phase reactions
Radiation
Strong buoyancy force support by solving for p_rgh
The reactingParcelFoam and reactingParcelFilmFoam tutorials have been combined
and updated.
