+The result of successful parsing of a valid path template can be represented by a list of sections, where each section is a list of index ranges, where index range is a tuple of (range_start, range_end). The length of the list of sections is also referred to as the "length of the template".

-The matching is to be performed against a list of integer values that represent a BIP32 path (or a portion of BIP32 path, for partial templates).
