Description

Building logical plans is arduous and a builder would make this nicer. Example:

let plan = LogicalPlanBuilder::new()
    .scan(
        "default",
        "employee.csv",
        &employee_schema(),
        Some(vec![0, 3]),
    )?
    .filter(col(1).eq(&lit_str("CO")))?
    .project(vec![col(0)])?
    .build()?; 

Note that I am already working on this and will have a PR shortly.
