* Basic support for memory allocation on GPU using CUDA unified memory. Partially addressing #284. IOR support completed.
* Support for GPU alloc in MDTest and MD-Workbench
* Option: support repeated parsing of same option (allows option sharing across modules).
* Checks for gpuDirect
* Integrate gpuDirect options and basic hooks, more testing to be done.
* POSIX: basic gpuDirect implementation working with fake-gpudirect library.
* CUDA allow setting of DeviceID for IOR (not yet MDTest).
* CUDA/GPUDirect Support --with-X=<path>
* Bugfix in option parser for flags that are part of an argument for an option, e.g., -O=1, if 1 is a flag it is wrongly assumed to be a flag.
