/**
* Defines a Long class for representing a 64-bit two's-complement
* integer value, which faithfully simulates the behavior of a Java "Long". This
* implementation is derived from LongLib in GWT.
*
* Constructs a 64-bit two's-complement integer, given its low and high 32-bit
* values as *signed* integers. See the from* functions below for more
* convenient ways of constructing Longs.
*
* The internal representation of a Long is the two given signed, 32-bit values.
* We use 32-bit pieces because these are the size of integers on which
* Javascript performs bit-operations. For operations like addition and
* multiplication, we split each number into 16-bit pieces, which can easily be
* multiplied within Javascript's floating-point representation without overflow
* or change in sign.
*
* In the algorithms below, we frequently reduce the negative case to the
* positive case by negating the input(s) and then post-processing the result.
* Note that we must ALWAYS check specially whether those values are MIN_VALUE
* (-2^63) because -MIN_VALUE == MIN_VALUE (since 2^63 cannot be represented as
* a positive number, it overflows back into a negative). Not handling this
* case would often result in infinite recursion.
*
* @class Represents the BSON Long type.
* @param {Number} low the low (signed) 32 bits of the Long.
* @param {Number} high the high (signed) 32 bits of the Long.

/**
* Defines a Timestamp class for representing a 64-bit two's-complement
* integer value, which faithfully simulates the behavior of a Java "Timestamp". This
* implementation is derived from TimestampLib in GWT.
*
* Constructs a 64-bit two's-complement integer, given its low and high 32-bit
* values as *signed* integers. See the from* functions below for more
* convenient ways of constructing Timestamps.
*
* The internal representation of a Timestamp is the two given signed, 32-bit values.
* We use 32-bit pieces because these are the size of integers on which
* Javascript performs bit-operations. For operations like addition and
* multiplication, we split each number into 16-bit pieces, which can easily be
* multiplied within Javascript's floating-point representation without overflow
* or change in sign.
*
* In the algorithms below, we frequently reduce the negative case to the
* positive case by negating the input(s) and then post-processing the result.
* Note that we must ALWAYS check specially whether those values are MIN_VALUE
* (-2^63) because -MIN_VALUE == MIN_VALUE (since 2^63 cannot be represented as
* a positive number, it overflows back into a negative). Not handling this
* case would often result in infinite recursion.
