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.
This is the first developer release of openPMD-api.
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.
