- The problem occurs when using atof to parse values such as "1e-39"
  since this is out of range for a float and _can_ set errno to
  ERANGE.

  Similar to parsing of integers, now parse with the longest floating
  point representation "long double" via strtold (guaranteed to be
  part of C++11) and verify against the respective VGREAT values for
  overflow. Treat anything smaller than VSMALL to be zero.

CONFIG: add settings for Cray compiler and cray mpich

See merge request !138

- the cray C/C++ compilers appear to be option-compatible with gcc.

- no wmake rules for 32bit builds (deemed to be unnecessary)

low-level binary Ostream output, additional stream classes

See merge request !156

- reduce coding clutter, avoiding allocated pointers when possible.
  IFstream and OFstream continue to use pointers since they handle
  compressed files, other streams can do without them.

- an output stream to a DynamicList

- these provide a similar functionality to string-streams, but operate
  on a externally provided memory buffer which can be used to reduce
  the amount of copying.

- classes were previously staged as part of the ADIOS community
  repository.

- for convenience and symmetry with OStringStream

STYLE: void return value for stream rewind() methods

- this makes it easier to design bidirectional streams

- low-level beginRaw(), writeRaw(), endRaw() methods.
  These can be used to directly add '()' decorators for serial output
  or prepare/cleanup parallel buffers.
  Used, for example, when outputting indirect lists in binary to avoid.

- now use public functions instead of direct access of private 'capacity_'
  information

- makes it easier to transmit or stream as a list of scalars

- the USE_OMP preprocessor symbol is also defined with the openmp
  compile flag to allow conditional compilation of openmp-specific
  code.

- better documentation of the file contents.
- quicker to obtain number of blocks without reading an entire file.

- used in various places to test if the input can be parsed as a
  label/scalar, so warnings tend to flood the output.

- be more explicit when encountering range errors

add support for KaHIP decomposition

See merge request !154

Feature list methods

See merge request !152

- refactor some common metis-like elements into the metisLikeDecomp
  abstract class.

Bugfix multi level decomp

Closes #620 and #619

See merge request !153

- previously when more than two levels were used.
  Now calculate the required final target domain segment directly.
