bve 0.0.1

//! Generic parser for key-value pair format. Not quite toml, not quite INI.
//!
//! No frills format. Does not deal with casing, comments, etc. That must be
//! dealt with ahead of time. This just deserializes the file as is. However
//! whitespace is trimmed off the edges of values
//!
//! There may be arbitrary duplicates.
//!
//! The first section before a section header is always the unnamed section `None`.
//! This differs from an empty section name `Some("")`
//!
//! ```ini
//! value1
//! key1 = some_value
//!
//! [section1]
//! value
//! key = value
//! key = value
//! ```
