//! **Stanhope**, named after the Stanhope Printing Press that improved upon Gutenberg's design by using sturdy iron and steel parts and hand levers to increase printing speed and quality.
//! 
//! This application takes an input argument file in a specific markup and produces a static, printable HTML page based on the markup file's contents.
//! 
//! The real power in this application is the markup language, which has these features:
//! * Single-purpose: just for writing processes that can be printed as documents
//! * General: suitable for writing any process
//! * Consistent: output branding and style is centrally controlled for 100% consistent processes in an organization's library
//! * *Visually* flexible: custom templates can mold the look/feel of the HTML produced
//! * *Format* rigid: we want process authors to think carefully to help operators in the field, and Stanhope forces authors to conform to pre-thought out process language and structure that solves this
