Adding elm-pb data_noflow case for workshop
Removing duplicate "test_suit_make"
Added Nick Walkden's blob model

2D model in a slab. Demonstrate basic blob dynamics and
use of PETSc solver for phi
Removing elm-pb/data_0flow directory
Modifying interchange-instability runcash.sh
Adding 6field-simple example, moving grid files

o Added simplified version of 6-field ELM simulation model

o Added g files and profiles for EAST simulations

o Moved binary grid files into examples/tokamak-grids, and added
  soft links to them from elm-pb and 6field-simple
Small fixes to reconnect-2field example
6field-simple update to collect-all.pro
Adding configure script for workshop

Links with SUNDIALS and PETSc in ~dudson/

Enables CVODE, IDA, PETSc and MUMPS interfaces
Added a Eigenvalue Solver for GLF ITG using matlab.
Improvements to blob2d example

Simplifying and adding more comments

Works with and without Boussinesq approximation
to produce propagating blob in a reasonable time (few minutes on single processor)
Important fix to petsc_laplace preconditioning

Forgot to assemble the vector after calling user
preconditioning function. Worked on some machines,
but not always.
Reverting changes to reconnect-2field
Reverting more changes to reconnect-2field

This version seems to work, but doesn't have some
external phi terms. Newer version moved to 2field-bc
Fix for reconnect-2field
Modifying checks for CVODE and IDA types
Fix to SUNDIALS type detection
Working on simplified Laplace solver

"cyclic" solver using the CyclicReduction class for the tridiagonal solve.
Once tested should be able to replace serial "tri" and parallel "spt" implementations.

Main aim is to simplify the structure of the code, to enable extensions.
Renamed Laplacian cyclic solver to avoid conflict with Parallel solver.

Apparently 'ar' overwrites objects stored in files with the same name
but different path -> no two .cxx files can have the same name in BOUT++
library
Cyclic Laplace solver now working

Passes test-laplace checks, run in serial or parallel. Once
tested further, this could replace "tri" and "spt" solvers.
