ORM aims to provide Table macro and auto migration

## Table macro

You need to specify `sql_type` to be something that each DB crate provides.

```rust

#[derive(Table)]

#[sql(table_name = "ex_1", sql_type = "...", primary_key = "pk")]

struct Ex1 {

    #[sql(size = 50, unique = true, not_null = true)]

    field1: String,

    aaaa: i32,

    pk: i32,

}

```

This example derives some useful mapper functions for this struct. See functions in [debil's docs](https://docs.rs/debil/).

## Accessor macro

Accessor macro provides safe way to access to each column. This is useful for constructing a query.

```rust

// Use Accessor derive here!

#[derive(Table, Accessor)]

#[sql(table_name = "ex_1", sql_type = "...", primary_key = "pk")]

struct Ex1 {

    field1: String,

    aaaa: i32,

    pk: i32,

}

// Use accessor! macro to access to a field with table_name prefixed

assert_eq!(accessor!(Ex1::field1), "ex_1.field1");

// If you only need field name, use accessor_name! macro

assert_eq!(accessor_name!(Ex1::aaaa), "aaaa");

// Or you can just call the field name function directly, which is derived by Accessor derive

assert_eq!(Ex1::field1(), "field1");

// accessor!(Ex1::foobar) <- compile error!

```
