 *
 * @param {object} properties An object containing the raw locale properties:
 *
 *        @param {String} properties.decimal_point
 *
 *        A string containing the symbol that shall be used as the decimal
 *        delimiter (radix character) in numeric, non-monetary formatted
 *        quantities. This property cannot be omitted and cannot be set to the
 *        empty string.
 *
 *
 *        @param {String} properties.thousands_sep
 *
 *        A string containing the symbol that shall be used as a separator for
 *        groups of digits to the left of the decimal delimiter in numeric,
 *        non-monetary formatted monetary quantities.
 *
 *
 *        @param {String} properties.grouping
 *
 *        Defines the size of each group of digits in formatted non-monetary
 *        quantities. The operand is a sequence of integers separated by
 *        semicolons. Each integer specifies the number of digits in each group,
 *        with the initial integer defining the size of the group immediately
 *        preceding the decimal delimiter, and the following integers defining
 *        the preceding groups. If the last integer is not -1, then the size of
 *        the previous group (if any) shall be repeatedly used for the

 *        grouping shall be performed.
 *
 *
 *        @param {String} properties.int_curr_symbol
 *
 *        The first three letters signify the ISO-4217 currency code,

 *        (normally a space).

 *        Each integer specifies the number of digits in each group, with the
 *        initial integer defining the size of the group preceding the
