Provide dependency information for opm-benchmarks
Depend on Boost::iostreams

The benchmark library uses Boost::iostreams to do decompression. Since
we only scan for the Boost dependency once, this submodule is added to
all of the projects in order to have a coherent dependency on Boost.
Uniformly raise Boost version requirement to 1.44

Commit 70505ff raised opm-core's "Boost" requirement to version 1.44
in order to reflect the requirements of the opm-parser module.  This
commit propagates that requirement to all other known modules.
Reformat prerequisite file according to convention

This commit makes a few adjustments to the white-space of file
'opm-parser-prereqs.cmake' to honour the conventions of the other
*-prereqs.cmake files within the OPM project's module suites.

No functional changes.
Depend on Boost.Iostreams

The benchmark library uses Boost::iostreams to do decompression. Since
we only scan for the Boost dependency once, this submodule is added to
all of the projects in order to have a coherent dependency on Boost.
Fix mis-merge.

In propagating the requirements for opm-benchmarks to the other
modules I accidentally removed the 'opm-parser' prerequisite (see
commit 86439d6 for details).  This commit restores that prerequisite.
Restore C++-11 checks

While reformatting the parser-prereqs file I accidentally replaced
the feature search 'CXX11Features' with 'CXX10Features'.  This
commit fixes that blunder.
Allow direct interpolation of props with new parser.

After transitioning to use the new parser, the SinglePvtDead class was never
used even when the 'samples' argument used to control usage was zero or negative.
The resulting construction of SinglePvtDeadSpline objects was then failing.

This change adds a new constructor to SinglePvtDead, and restores the ability
to control spline usage with the samples argument.
Merge pull request #503 from bska/503_cmake

[CMake] Propagate Boost.Iostreams to all modules
Merge pull request #504 from atgeirr/allow-no-spline-new-parser

Allow direct interpolation of props with new parser.
add variants of all methods which take a deck of the new parser to the well handling code

this is supposed to be a temporary work around for not requiring the
old parser. Most of this code can be removed after the new well
handling code has landed. (which might be still some time, alas.)
add variants of all methods which take a deck of the new parser to the EclipseWriter

this might need some additional patches as the current EclipseWriter
is taking advantage of quite a few features in EclipseGridParser, most
notably the getValue<T>() template method.
convert more exceptions to compile-time warnings with scary run-time statements

with this, norne runs up to the point where the initial solution is
written...
EclipseWriter: make it possible to write the Norne data

this requires that the PERM* are individually checked and that all
cells are always written. Also, there seems to be a problem with the
summary output which I have not investigated further...
