Added getGlobalDofNormals() and getFlatLocalDofNormals() methods to Space.
Added AcaOptions.firstClusterValue parameter (for debugging ACA).
GridFunction::evaluateAtSpecialPoints() doesn't rely any more on the
implementation detail that EntityIterator returns entities with consecutively
increasing indices.
Added unit tests checking the implementation detail that
EntityIterator returns entities with consecutively increasing indices.
Some parts of BEM++ still implicitly rely on it.
Incompatible change:
ElementaryAbstractBoundaryOperator::assembleWeakFormInternal() and
AcaGlobalAssembler::assembleDetachedWeakForm() now take a context object
rather than just AssemblyOptions.

Added a space of discontinuous piecewise linear functions.

The Space class has a new member, discontinuousSpace(), which returns
an object representing the space with the same span, but basis functions
defined on single elements only.
Removed an unnecessarily conservative assertion from NumericalTestTrialIntegrator.
Added a functor choosing a particular term from a scalar product of test
and trial function transformations.

Added a function calculating the Cholesky decomposition of a (disordered)
block-diagonal sparse matrix.
Added a function calculating (naively) the inverse of a (disordered)
block-diagonal sparse matrix.
Added a GeneralElementaryLocalOperator class.
Reimplemented the Laplace-Beltrami operator using the new general local op.
Extended the suite of operator overloads for shared_ptr<DiscreteBoundaryOperator>.
BoundaryOperator can now be configured to store its weak form only as a weak pointer.

Small changes for compatibility with new Epetra.
