0bdc5d53c4 Changed: Moved some methods related to adaptive simulation 
from SIMoutput to SIMgeneric such that SIMoutput only deals
with result output, and not much else. Retained virtual
interfaces for some methods that are used by AdaptiveSIM.

48d8fc58ac Fixed: Resizing the rectangular search box for elements in domain. 
Added: Option to search for domain elements containing (or close to)
the reference point, instead of using a rectangular box.

de6fa008f0 Added: Extraction function for point-wise stress evaluation. 
Changed: Don't have to use getPatch() when the patch index argument
is a local index which clearly is within the valid range,
then address myModel directly instead.
Also a few more range-based for loops.

56fe8b0530 Fixed: Result point evaluation for multi-patch models. 
Since the result points are evaluated patch-wise, we need
to augment the results values of each patch to get the total.

4c9bb55396 Added: virtual methods realSolution(s) in MultiStepSIM. 
This facilitates that the actual solution vectors to be used for post-
processing are not the same as used during the time integration itself.

0dc1c9cbce Fixed: Incorrect sanity check correction. 
It turns out I was wrong in e3da110cb9.
The check should instead use the number of coefficient in the patch,
which will work both for mixed and regular problems.
The check against MLGN.size() is still needed as a secondary condition,
in case of dirichlet conditions in local axes (with extra nodes around).

e3da110cb9 changed: adjust sanity check in ASMxD::updateCoords 
for mixed discretizations there are additional fields present.
to avoid failing in this case, accept any vectors of sufficient size
instead of putting a requirement on the exact length.

63c8f976b3 changed: use extractPatchSolution for updateGrid with mixed 
use of an additional MADOF is required

c71ced943f Fixed: Wrong input to an evalPoint call when calculating element center. 
Added: Implementation of ASMu2D::constrainNode searching for matching nodes.
This works (although not that efficiently) for interpolatory C0-points,
and is handy for doing adaptive analysis of the single-patch L-shape, etc.

c21ec8a96e Added: virtual method evalSol2 and non-virtual IntegrandBase::evalSol1. 
The latter method can be used when the secondary solution depends on
the first primary solution vector only (which covers most cases).
Then the integrand can override the evalSol2 method instead of evalSol
such that they don't need to deal with the element-level extraction
of solution vectors themselves (the default evalSol will do it).
Also extended the doxy for the initElement and evalSol methods.

24ab9e6503 Changed: The enum for system matrix type is now in LinAlgEnums.h 
and we don't need a separate system vector type as
it is directly linked to the specified matrix type.
Added: Option to use UMFPACK in the L2-projection.

a7b9bd3137 Changed: Put the linear system type flag inside LinSolParams.

fc38e96b3b added: full support for schur-complement block preconditioners

possible. now, any approximation can be used for A^-1.

4cc284a298 Changed: Use ItgPoint instead of FiniteElement in Field unit tests. 
Moved the ASMSquare and ASMCube definitions to separate header files
to enable reuse in other tests. There was a bug in ASMCube also.

70176f1408 Added: Class ItgPoint representing an integration/evaluation point, 
the class FiniteElement then inherits ItgPoint.
