Explain how numbers are handled

[taowen]

• read(Number.class) support int/float/long/BigDecimal #61
• JsonIterator's read() looses precision when encounters a large long value #60
• read large number as object #74
• JsonIterator.deserialize long is converted to double #147

[taowen]

In short, use Any instead of Object, to control how numbers decoded. By default, all number will be decoded as Double. This is the behavior of jackson/gson as well. I will update jsoniter.com tomorrow on this.

This is not the behaviour of jackson also. I replaced jackson with jsoniter and that's how I encountered #147

[taowen]

@tomcashman you are right, seems like jackson will choose Integer/Long/BigInteger automatically
