Comment: add a section on NULL values (HIVE-3386)

...

Floating point literals are assumed to be DOUBLE. Scientific notation is not yet supported.

Missing values are represented by the special value NULL. To import data with NULL fields, check documentation of the SerDe used by the table. (The default Text Format uses LazySimpleSerDe which interprets the string \N as NULL when importing.)
