/**
 * Check and identify the section header parts via tokenizing the parts and return them as strings.
 * @param rawHeaderLine Raw line with the section header where the header
 * marker will be identified. E.g. does the header start with '^^^' or '^3'
 * and then some identifier.
 *
 * Below, copied from YINI Specification v1.0.0 Beta 7.
 * Form 1: Identifier of Simple Form:
 * - Keys must be non-empty.
 * - Keys are case-sensitive (`Title` and `title` are different).
 * - Can only contain letters (a-z or A-Z), digits (0-9) and underscores `_`.
 * - Must begin with a letter or an underscore `_`.
 * - Note: Cannot contain hyphens (`-`) or periods (`.`).
 *
 * Form 2: Backticked Identifier:
 * - A phrase is a name wrapped in backticks  ``` ` ```.
 * - Backticked identifiers must be on a single line and must not contain tabs or new lines unless using escaping codes, except for ordinary spaces.
 * - Special control characters (U+0000–U+001F) must be escaped.
 *
 * @note Implemented without regexp to keep it less cryptic, etc.
 * @note Returns the parts as strings; each part needs to be analyzed separately against the contraints in the specifications.
 * @returns An object with the identified header parts: marker characters, parsed name, and parsed level string.
