847	VERY IMPORTANT: Corrected issues with 4D-Var weak constraint	arango		"Fixed couple of issues in the weak constraint 4D-Var algorithm:

* Removed some legacy code in routines '''forcing.F''' and '''tl_forcing.F''' when processing the impulse forcing for the weak constraint 4D-Var formulation.  The legacy code that included the forcing for '''ubar''' and '''vbar''' in 3D solutions were removed from '''forcing.F''' when '''SOLVE3D''' is activated. Similarly, the forcing for '''tl_ubar''' and '''tl_vbar''' was removed from '''tl_forcing.F'''.

* Added logic to '''def_impulse.F''', '''get_data.F''', '''set_data.F''', '''tl_get_data.F''', '''tl_set_data.F''', and '''checkvars.F''' to avoid processing the weak constraint impulse forcing for '''ubar''' ('''tl_ubar''') and '''vbar''' ('''tl_vbar''') when '''SOLVE3D''' is activated.

Many thanks to Andy Moore for his help in tracking this bug."	bug	closed	major	Release ROMS/TOMS 3.9	Adjoint	3.9	Fixed
