 * Parses string hash files. File format is as such:
 *
 *      DefaultKeyValue
 *      KEY: Value
 *      KEY2: Value2
 *      --MULTILINE-KEY--
 *      Multiline
 *      value.
 *
 * Which would output something similar to:
 *
 *      array(
 *          'ID' => 'DefaultKeyValue',
 *          'KEY' => 'Value',
 *          'KEY2' => 'Value2',

 *      )
 *
 * We use this as an easy to use file-format for configuration schema
 * files, but the class itself is usage agnostic.
 *
 * You can use ---- to forcibly terminate parsing of a single string-hash;
 * this marker is used in multi string-hashes to delimit boundaries.
