Stg type abstraction

Setting is the trait that needs to be implemented for types for them to be turned into Stg

StgError Error on conversion from Stg or T<&Stg> into S: Setting

StgTrait Trait implement

§Example use of Stg in an Account:

use hashmap_settings::{account::Account,stg::{Setting,Stg,StgTrait,StgError}};
//creating an account
let mut account = Account::<(),&str,Stg>::default();

//inserting values of distinct types
account.insert("Number of trees",5.stg());
account.insert("Grass color","green".to_string().stg());
account.insert("Today is good",true.stg());

//getting values from the account
let today_bool: bool = account.get(&"Today is good").unstg()?;
let grass_color: String = account.get(&"Grass color").unstg()?;
let trees: i32 = account.get(&"Number of trees").unstg()?;

//example of using the values
print!("It's {today_bool} that today is a wonderful day,
    the grass is {grass_color} and I can see {trees} trees in the distance");
