/**
 * The [TomlAnalyser] class is responsible for parsing TOML (Tom's Obvious, Minimal Language) code and converting it into a
 * [CodeContainer] object.
 *
 * Example usage:
 * ```kotlin
 * val container = TomlAnalyser().analysis("title = "TOML Example"")
 * assert(container.Fields.size == 1)
 * assert(container.Fields[0].TypeKey == "title")
 * assert(container.Fields[0].TypeValue == "TOML Example")
 * assert(container.Fields[0].TypeValue == "String")
 * ```
