and slightly improve comments and layout

Add option to parallel_self_test.pt to run in serial mode for debugging

In parallel_self_test.py write make output to file "make_check_output"

Instead of dumping it to /dev/null. Useful if make failures are not
reproducible for some weird reason.

In parallel_self_test.py always get the absolute path (less error prone)

In parallel self tests: add option to build but not run tests

Clean up of some of my (David) code in oomph-lib core

* Move interpolator.h to generic.

* Clean up comments in interpolator.h.

* Add ability to interpolate time and space derivative of values
  (i.e. d2v/dxdt).

* Move some large functions from midpoint_method.h and poly_interp.h to .cc
  files.

* Clean up comments and add paranoid checks in poly_interp.h.

Add a function to get the (unmangled) type name of an object as a string

git-svn-id: svn+ssh://vummath.ma.man.ac.uk/home/svn-oomphlib/public/trunk@752 595e1d82-adf1-4282-bac7-b6073fa2ca8e
Additional capabilities for interpolator class

* Can optionally set the timestepper to be used

* Store local position

* Needed to make nprev_values_for_value_at_evaluation_time() const

git-svn-id: svn+ssh://vummath.ma.man.ac.uk/home/svn-oomphlib/public/trunk@753 595e1d82-adf1-4282-bac7-b6073fa2ca8e
Move undo_make_steady up into Timestepper base

* Avoids duplicate code - all implementations did the same thing

* Virtual so still easy to overload if needed

* Also very slightly increased tol in fpdiff in axisym_navier_stokes/torus
  Not sure if this is related to this change but it was needed to make the
  test pass on my machine. Changed zero from 1e-12 -> 1.1e-12 .

Add paranoid check for empty matrix when running SuperLu

Otherwise we get a segfault inside SuperLu, with no easy way to find out
what went wrong.

Make vector time_derivative calc use individual time_derivative function

Cleaner code and easier to overload.

Also fixed some comments.

Initial commit of explicit timestep predictor work

* Idea is to be able to use a (higher order) explicit time stepper to
  estimate the local trunction error for time adaptivity.

* Working test in demo_drivers/unsteady_heat/two_d_unsteady_heat_midpoint

Combine rebuild_global_mesh() and merge_meshes() functions

They were copy pasted from each other so might as well be one function for
consistency.

Improve check-makefile-subdirs.py

* Better formatted output

* Smarter input

* Use function from parallel_self_test.py

Add safe global_to_node lookup in SumOfMatrices code

* Rename old method to unsafe_...

* Safe version is better for normal use (throws error on failure) but unsafe
  (return -1 on failure) is needed for some things.
