Change log: Moving to C++17. This means that the code can only be build using C++17 compilers (e.g. g++ >8 and Visual Studio 2017, clang > 5), fixing related bugs - (#698, #629, #641) Removing an explicit dependency on boost (all the filesystem operations are performed using std::filesystem or boost::filesysteme). If boost is available it will used boost:filesystem, otherwise std::filesystem (this requires C++17) Visual Studio 2017 is now the main version for Visual Studio builds, VS 2015 is no longer supported Updating OpenCV to 4.1 version (#511) Fixing a bug with output images when using GUI (#694) Updating RAWImage - #609, so it can be initialized from System.Drawing.Bitmap directly Fixing overlap detection for multi face tracking (#693)

// GMetaArg is an union type over descriptions of G-types which can serve as
|
|
// GComputation's in/output slots.
|
|
//
|
|
// GMetaArg objects are passed as arguments to GComputation::compile()
|
|
// to specify which data a compiled computation should be specialized on.
|
|
// For manual compile(), user must supply this metadata, in case of apply()
|
|
// this metadata is taken from arguments computation should operate on.
|
|
//
|
|
// The first type (monostate) is equal to "uninitialized"/"unresolved" meta.
