 For the byte array type, it encodes the length as a 4 byte little
 endian, followed by the bytes.
 
-### GroupVarInt:
-
-Supported Types: INT32, INT64

-
-32-bit ints are encoded in groups of 4 with 1 leading bytes to encode the
-byte length of the following 4 ints.
-
-64-bit are encoded in groups of 5,
-with 2 leading bytes to encode the byte length of the 5 ints.  
-
-For 32-bit ints, the leading byte contains 2 bits per int.  Each length
-encoding specifies the number of bytes minus 1 for that int.  For example
-a byte value of 0b00101101, indicates that:
-
-  * the first int has 1 byte (0b00 + 1), 
-  * the second int has 3 bytes (0b10 + 1),
-  * the third int has 4 bytes (0b11 + 1)
-  * the 4th int has 2 bytes (0b01 + 1)
-
-In this case, the entire row group would be: 1 + (1 + 3 + 4 + 2) = 11 bytes.  
-The bytes that follow the leading byte is just the int data encoded in little
-endian.  With this example:
-
-  * the first int starts at byte offset 1 with a max value of 0xFF,
-  * the second int starts at byte offset 2 with a max value of 0xFFFFFF,
-  * the third int starts at byte offset 5 with a max value of 0xFFFFFFFF, and
-  * the 4th int starts at byte offset 9 with a max value of 0xFFFF. 
-
-For 64-bit ints, the lengths of the 5 ints is encoded as 3 bits.  Combined,
-this uses 15 bits and fits in 2 bytes.  The msb of the two bytes is unused.
-Like the 32-bit case, after the length bytes, the data bytes follow.
-
-In the case where the data does not make a complete group, (e.g. 3 32-bit ints),
-a complete group should still be output with 0's filling in for the remainder.
-For example, if the input was (1,2,3,4,5): the resulting encoding should
-behave as if the input was (1,2,3,4,5,0,0,0) and the two groups should be
-encoded back to back.
