Compares the given values using <code>===</code> and <code>></code>.

@param {any} vValue1
  the first value to compare
@param {any} vValue2
  the second value to compare
@return {int}
  the result of the compare: <code>0</code> if the values are equal, <code>-1</code> if the
  first value is smaller, <code>1</code> if the first value is larger, <code>NaN</code> if
  they cannot be compared
