058f6a8b71 Fixed a bug in the void-zone version of AMS, which sometimes produced 
non-symmetric preconditioner.

d60adad0c5 Added new smoothers: Chebyshev (to AMG and AMS), FCF-Jaconi, and CG. 
Added threaded version of L1-Jacobi.

9f26a7739a Changed 'cp -fpd' to 'cp -fpPR' for better portability. 
This should work on the Mac now in particular.

8ed12c2264 Added the release number to the names of hypre shared libraries (see [issue181]). 
Also removed the HYPRE_LSI library because it was nearly identical to HYPRE.

09e80c238a Added a user function that project a given vector onto the compatible 
subspace for problems with zero-conductivity regions. This is useful for
visualization of the solution, which otherwise will be polluted by kernel
components.

f773fd6a32 Moved the solver_counter from AMSSolve() to the ams data structure. This 
way multiple Setup()+Solve() calls will give identical results.

7946048c89 Several improvements in the zero-conductivity-regions version of AMS, which 
should give a cheaper and more robust solver on most problems.

b88deab80f Added a more robust version of AMS for problems with zero-conductivity regions, 
where the matrix is singular Ker(A)=Ran(G0).

To use this version, provide a list of the interior nodes in the zero
conductivity region using AMSSetInteriorNodes(). This will constructs G0 and AMS
for A+G0G0^T.  For compatibility, the PCG residual is periodically projected
onto Ker(G0^T).  This is done in AMSSolve() and can be adjusted with
AMSSetProjectionFrequency().

c4d9da0d6c Improved version of the AMSConstructDiscreteGradient() function, which 
generates the discrete gradient matrix based on edge information provided
by the user. This simplifies the use of AMS.

These two interfaces (search for 'RDF') are probably not useful.
