> Let's extend native support for Numeric types.
> * Number( n ) is an {{n}}-bytes two-complement integer signed value encoded in the varlong style 
> (so that Number(4) can be mapped to integer and Number(8) can be mapped to long during (de)serialization). 
> * Larger numbers can be represented as {{BigInteger}}.
> * The Number( n ) is a varlen type, so it will take two additional bytes in the varlen table, so types smaller than Number(4) are better represented by {{byte}} and {{short}} and {{int}} types as their fixlen encoding takes exactly 1, 2, 4 bytes respectively.
> * Decimal is a direct mapping to BigDecimal value.
