Lib.rs

This version, have no any difference compared with version 0.1.4 and 0.1.3 , except for the
revised documention.

A simple macro to generate a specified sql when we have a struct A.

For example:
#[derive(TableCreator)]
struct A <'a, T>{
#[table_ignore]
a: i32,
b: String,
c: &'a T
} printfln!("{}", A::<'somelifetime, SomeType>::table_creat_sql()}

the output is :
CREATE TABLE IF NOT EXISTS A (id SERIAL PRIMARY KEY, b TEXT , c SomeMatchedSqlType )

The elements , with #[table_ignore], will be ignored.

It just support some Sqlite's sql types:
i32| u32 | i64 | u64 => INTEGER, f32 => REAL
f64 => REAL
String | str => TEXT
bool => BOOLEAN
NaiveDate => DATE
NaiveDateTime => TIMESTAMP
