WIP: Refactoring dnsfoam
UEqn.H file is created.
Its content is moved from dnsFoam.C
STYLE: Newline is removed.
ENH: Delete globalProperties.H.
Its content is appropriately moved into UEqn.H
ENH: pEqn.H is created. Its content is moved from dnsFoam.C.
ENH: UEqn.H and pEqn.H are added.
ENH: Contents of readTurbulenceProperties.H and readTransportProperties.H are added.
ENH: Delete readTurbulenceProperties.H. Content is moved into createFields.H
ENH: Delete readTransportProperties.H Content is moved into createFields.H
ENH: Note is added for highlighting the requirement for optional FFTW lib.
ENH: Update dnsFoam.C. Content between createFields and the first while-loop is moved into createFields.H.
ENH: Code move into createFields.H
Content between createFields and the first while-loop in dnsFoam.C is moved into createFields.H.
STYLE: Remove redundant tabs
ENH: Remove redundant tabs in UEqn.H
ENH: Add newline to UEqn.H to avoid wmkdepend warning
ENH: Add last new line into createFields.H to avoid wmkdepend warning
ENH: Add last new line into pEqn.H to avoid wmkdepend warning
ENH: include preprocessor directives are corrected
