Added basic serialization support

[vsg-dev]

Description

Introduction of serailization support for vsg::Object and it's subclasses.

New base vsg::Input and vsg::Output classes provide the abstraction from the task of input and outputting raw data.

The AsciiInput/AsciiOutput classes provide preliminary .vsga native ascii file support.

The BinaryInput/BinaryOutput classes provide preliminary .vsgb native binary file support.

include/vsg/type_name.h now provides a vsg::type_name<>() templated interface for getting human readable type names.

• [x ] New feature (non-breaking change which adds functionality)

How Has This Been Tested?

The vsgExamples/vsgio testbed application, tests include 10 level deep quad tree:

Reading and writing binary files:

vsgio -l 10 -o level_10.vsgb
vsgio -i level_10.vsgb -o level_10_result.vsgb

Reading and writing ascii files:

vsgio -l 10 -o level_10.vsga
vsgio -i level_10.vsga -o level_10_result.vsga
