Patches, Const Scalars, Py Containers

Scalar records properly support const-ness. The Particle Patch load interface was changed, loading now all patches at once, and Python bindings are available. Numpy dtype is now a first-class citizen for Python Datatype control, being accepted and returned instead of enums. Python lifetime in garbage collection for containers such as meshes, particles and iterations is now properly implemented.

Refactored Type System

The type system for Datatype::s was refactored. Integer types are now represented by SHORT, INT, LONG and LONGLONG as fundamental C/C++ types. Python support enters "alpha" stage with fixed floating point storage and Attribute handling.

Improved output handling

Refactored and hardened for fileBased output. Records are not flushed before the ambiguity between scalar and vector records are resolved. Trying to write globally zero-extent records will throw gracefully instead of leading to undefined behavior in backends.

Refined fileBased Series & Python Data Load

A specification for iteration padding in filenames for fileBased series is introduced. Padding present in read iterations is detected and conserved in processing. Python builds have been simplified and python data loads now work for both meshes and particles.

Py Attributes, Better FS & Checks

This release exposes openPMD attributes to Python. A new independent mechanism for verifying internal conditions is now in place. Filesystem support is now more robust on varying directory separators.

Initial Numpy Bindings

Adds first bindings for record component reading and writing. Fixes some minor CMake issues.

ADIOS1 Build Fixes & Less Flushes

We fixed build issues with the ADIOS1 backend. The number of performed flushes in backends was generally minimized.

Thanks to Fabian Koller and Axel Huebl for contributing to this release!

First developer release

Both HDF5 and ADIOS1 are implemented as backends with serial and parallel I/O support. The C++11 API is considered alpha state with few changes expected to come. We also ship an unstable preview of the Python3 API.
