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