Removed the forcing of gravity to be zero. Added option use_gravity. The gravity is set to the standard value
Add eclipse format output to SteadyStateUpscalerImplicit.

Option activated with output_ecl=true.

Requires libert support in opm-core. If opm-core has not been compiled
with the necessary --with-ert=</usr/local or similar> option, the program
should abort upon trying to write the output. Hopefully this enables to
keep ERT-detection macros and the like out of this module.
added: utilities to find complex eigenvalues of dyn and field matrices

this is missing in dune.

process has been started to get this integrated upstream
http://www.dune-project.org/flyspray/index.php?do=details&task_id=1186&project=1
fixed: move Vector type under the correct namespace
added: MatrixOps::extractDiagonal

extracts the diagonal of a matrix as a new matrix
added: MatrixOps::saveAsc

save a matrix as a dense asc file for easy import into e.g. octave
note this is only useful for debugging small systems, as the asc
files grow very big and unmanageable
fixed: make sure we do not dereference null ptrs
added: support for higher order lagrangian multipliers

- add PN shape function support
- make the way we group boundary elements into pillars more robust
- use the new shape functions in mortar matrix assembly
- add options to specify multiplier order (defaults to linears for now)
changed: refactor method setting into an enum instead of a set of bools
added: method=none

use this to apply no periodicity approach. useful for debugging
quell compiler warnings (sign/unsigned mismatch, unused variables)
fixed: make sure we load vectors
added: warn if volume cell is degenerated

also gives the collapse tolerance that will get rid of the cell
fixed: warn and exit instead of segfault if model uses more materials than is in rock list
changed: use human friendly 1 based loadcase numbering

Postpone incorporation of user-supplied surface tension to the end
Merge remote-tracking branch 'hnil/master'
Fixed missing member, parameter name and changed gravity sign.

Assumes now that gravity should be positive in the z direction.
