- EclIO classes have been updated to support arrays with size beyond numeric limits for integers
- Output of arrays having 2^31 or more elements is facilitated by using a pair of headers
- The first header is of type X231, second should have the actual type
- The large array format extension is documented in the Eclipse File format manual
This makes the facility usable for the restart read/write code.
Specifically, import the I/O classes into namespace Opm::ecl, and
place the files in physical location opm/io/eclipse, and move the
test utilities to new top-level directory 'test_util/'. While here,
discontinue the 'testutil' static library since most of its features
are now available in the main 'opmcommon' library. This does entail
compiling a few of the test_util/ CPP files multiple times, and
adding the objects to each executable independently.
