[boost] Author assistance for WG21 display content

Hello everyone, My name is Rob Beeston, and I’m the Product and Creative Director for C++ Alliance. I’m currently making arrangements for the upcoming WG21 event, and could use some help from some of the authors. We will be making posters, similar to this mockup ( https://downloads.cppalliance.org/images/boost-poster.png) to highlight the following libraries at the event: Hash2 Math Parser Scope Unordered Each poster would need a brief description, a longer explanation (perhaps 1-2 short paragraphs of what it does and/or how it works) and a code snippet that would best represent how to use it. Thanks and I’m looking forward to working with you. Rob
