 6:  * This class provides the metadata for the MaxMind DB file.
 7:  *
 8:  * @property int nodeCount This is an unsigned 32-bit integer indicating
 9:  * the number of nodes in the search tree.
10:  * @property int recordSize This is an unsigned 16-bit integer. It
11:  * indicates the number of bits in a record in the search tree. Note that each
12:  * node consists of two records.
13:  * @property int ipVersion This is an unsigned 16-bit integer which is
14:  * always 4 or 6. It indicates whether the database contains IPv4 or IPv6
15:  * address data.
16:  * @property string databaseType This is a string that indicates the structure
17:  * of each data record associated with an IP address. The actual definition of
18:  * these structures is left up to the database creator.
19:  * @property array languages An array of strings, each of which is a language
20:  * code. A given record may contain data items that have been localized to
21:  * some or all of these languages. This may be undefined.
22:  * @property int binaryFormatMajorVersion This is an unsigned 16-bit
23:  * integer indicating the major version number for the database's binary
24:  * format.
25:  * @property int binaryFormatMinorVersion This is an unsigned 16-bit
26:  * integer indicating the minor version number for the database's binary format.
27:  * @property int buildEpoch This is an unsigned 64-bit integer that
28:  * contains the database build timestamp as a Unix epoch value.
29:  * @property array description This key will always point to a map
30:  * (associative array). The keys of that map will be language codes, and the
31:  * values will be a description in that language as a UTF-8 string. May be
32:  * undefined for some databases.
