Add meta data writer

This MR adds a new feature to VirtualFluids: a Meta-Data Collector and Writer. The data collection is located in basics/MetaData/MetaData.h. It contains the data and a logging mechanism for pre- and post-simulation logs. Additionally, YAML_MetaData creates a yaml file from this data. This file is written into the standard output folder.

For example a DrivenCavity file can look like this:LidDrivenCavity.yaml

The MetaData class is in use in the gpu_core module, but not in cpu_core yet. It gpu_core a MetaDataCreator was added, which creates MetaData from Parameter. Everything is instantiated in the Simulation class. With this, all gpu apps automatically make use of this new functionality.
