One or more new changesets pushed to the primary DOLFIN repository.
A short summary of the last three changesets is included below.

description:
Implement boundary conditions:
 - Application implemented in NewBoundaryCondition::apply()
 - New class SubDomain makes definition of sub domains easy
 - Solution vector looks correct for Poisson demo!

Next we need to fix the export to vertex values to plot
the solution. Also need to update the PDE classes.
