Add more examples

[Manu343726]

We need more examples covering other Boost libraries. Not only to show biicode users examples of Boost, but also to test if all libraries work on all the supported platforms/toolsets.

Since 80% Boost is header only, please focus on Boost libraries that should be built. From the docs:

• Boost.Chrono
• Boost.Context
• Boost.Filesystem
• Boost.GraphParallel
• Boost.IOStreams
• Boost.Locale
• Boost.MPI
• Boost.ProgramOptions
• Boost.Python
• Boost.Regex
• Boost.Serialization
• Boost.Signals
• Boost.System
• Boost.Thread
• Boost.Timer
• Boost.Wave

And maybe in the future the optionals:

• Boost.DateTime
• Boost.Graph
• Boost.Math
• Boost.Random
• Boost.Test
• Boost.Exception
