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
