TODO list for the simplest groundwater flow simulation

Tasks to be done for being able to simulate the simplest groundwaterflow (let's say non-parallel, 2d, steady-state). Proposed deadline for this milestone is 30 September 2013.

Task	Who	When
merge BaseLib from norihiro's branch	LB et al	Dec 2012
add SystemOfLinearEquations in MathLib	NW, WW, TF, DN	Dec 2012
reorganize MathLib/LinAlg	NW, TF, DN	Jan-June 2013
-> add Lis interface	NW, TF, DN	June-July 2013
-> add PETSc interface	WW	Nov 2013-
add AssemblerLib (interface, serial)	NW, TF, DN	Feb-Aug 2013
-> add domain decomposition version	WW
add FemLib (2d quad, gauss integration)	NW	Aug-Sep 2013
add GW test	TF	Oct 2013-
-> performance test / optimisation of the serial version	TF
-> scalability test with PETSC	WW
-> decide a library for local matrix and vector	HS, DN et al
