* Error introduced as part of recent UZF refactoring
* Closes MODFLOW-USGS#273

Implemented new check in develop mode so code bombs with error if memory manager variable not deallocated

…GS#279)

* single code base for writing binary budget files for advanced packages
* single code base for creating and writing budget tables to list file for advanced packages
* implemented for MAW, UZF, LAK, SFR, and MVR
* closes MODFLOW-USGS#277
* update mf6exes from 2.0 to 3.0
* will allow generalized transport calculations for advanced packages

…W-USGS#281)

* refactor(advanced packages): modify advanced packages to read all static data as part of df()
* modify setup_budobj to include the connectivity so that it is available to other models

# Conflicts:
#	msvs/mf6.vfproj
#	src/Utilities/BudgetTerm.f90

…W-USGS#288)

* User-specified values for RAINFALL, EVAPORATION, RUNOFF, INFLOW, and WITHDRAWAL must be positive.  The program worked if these values were negative, but that doesn't necessarily make sense and is probably an input error.
* Updated definition file to reflect these changes
* Corrected minor typo in lake definition file
* Updated release notes to reflect this change
* Close MODFLOW-USGS#287

* Also includes a reach volume term written as an aux variable.  This is needed for transport.
* initialize str so non-ascii characters don't show up in output files
* updated notes for these changes

…SGS#308)

Code was incorrectly calculating cell center elevations when nozee was .false.  This error would have affected XT3D simulations with unconfined flow and non-zero values specified for ANGLE2 in the NPF Package.  It also would affect dispersive transport with XT3D for unconfined conditions.

Add traps to catch 1) skin factors that are <= 0 when using the SKIN
conductance equation and 2) and negative saturated conductances values.

Closes MODFLOW-USGS#305

…OW-USGS#303)

Full implementation for SFR package. Partial implementation for LAK, MAW, and UZF packages.

…ODFLOW-USGS#315)

Also fix some budget reporting issues in the MAW package

* change order of time series interpolation so aux is done first in case it is an auxmult column
* partially addresses MODFLOW-USGS#314
* updated release notes
