v0.1.0

Implement the first version of this library, venndb.
Released as venndb (0.1.0) and venndb-macros (0.1.0).

API Example:

use venndb::VennDB

#[derive(Debug, VennDB)]
pub struct Employee {
    #[venndb(key)]
    id: u32,
    name: String,
    is_manager: bool,
    is_admin: bool,
    #[venndb(skip)]
    foo: bool,
    #[venndb(filter)]
    department: Department,
}

fn main() {
    let db = EmployeeDB::from_iter(/* .. */);

    let mut query = db.query();
    let employee = query
        .is_admin(true)
        .is_manager(false)
        .department(Department::Engineering)
        .execute()
        .expect("to have found at least one")
        .any();

    println!("non-manager admin engineer: {:?}", employee);
}

This API, using nothing more then a derive macro allows to:

• store rows of data in a generated database;
• query the database using the defined filter fields;
• get references to rows directly by a key;

The crate comes with examples and a detailed README.

Please share with us if you have any feedback about this first version,
how you are using it, what you would like different, etc.
