Fixed spelling of Moffatt.
Added boost to CMakeLists.txt.
Added ad hoc "symmetric refinements" option to LidDrivenFlowRefinementStrategy.
Added extended precision Gram matrix inversion option to BilinearForm.  (Unclear if/how well this works.)
Adedd cholesky_test.cpp.
Fixed spelling of "Moffatt."
Many changes and fixes to NavierStokesCavityFlowDriver, including adoption of Jack Poulson's choice.
Rewriting Solution's condition # estimator, but it still isn't worth much.  Also moved implementation of Solution::setWriteMatrixTo*() methods out of header into .cpp file.
Added support for writing stiffness matrices to disk to HConvergenceStudy.
Made the second argument to diagonalContourLevels() explicit.
Added support for removing zero mean constraints, as well as imposing single-point constraints, to BCEasy.
Added support for the unit-compliant graph norm to Stokes VGP.
Added support for unit-compliant graph norm to StokesStudy.
Various modifications to StokesBackwardFacingStepDriver.
Various modifications, including support for extended precision Gram matrix inversion, to StokesCavityFlowDriver.
Added CamelliaCholesky.  (Not yet used anywhere.)
