                 Changes in version 2.0.0 (2022-02-24)                  

  - Print Methods
    
     * Created print.ldBounds: almost identical to summary 
            (just leaves off the exit probabilities)
        
     * Created print.ldPower: almost identical to summary
            (just leaves off the exit probs, and puts the
            lower/upper probs up with the boundaries, instead
            of separating)
        
     * Edited summary.ldPower: to give power when drift is
            known (put space before probs table)

  - Better two-sided bounds and defaults rather than weird parameters
    
     * Created sides argument for ldBounds
     
     * Added ability to specify the number of looks, which
            then automatically creates equally spaced analysis
            times
        
     * Sides=2, but with only one alpha, etc, creates
            symmetric bounds, splitting the provided alpha in
            half for each, upper and lower bounds
        
     * Print and summary functions updated to account for
            this

  - ldPower to use output from ldBounds
    
     * ldPower can now accept an ldBounds object as the first
            argument, in which case, it does not require za,
            zb, t, t2
        
     * Defaults to drift=0 when nothing is specified

  - Nominal alpha level at each look provided (for one-sided or
    symmetric bounds)
    
     * ldBounds now has additional value: nominal alpha at
            each look.
        
     * Summary.ldBounds displays this

  - asf changed from asf/alpha to asf
    
     * asf now uses just asf rather than asf alpha (this
            was only a change to alphas function)

  - Weird integer errors
    
     * ldBounds and alphas now have checks that take into
            account floats

  - Ability to specify non-alpha spending boundaries
    
     * Created new function commonbounds to calculate
            Pocock or O{'}Brien-Fleming (non-alpha-spending)
            bounds at equally spaced times.
        
     * These also become ldBounds objects
     
     * Adjusted print and summary functions to accommodate

  - Calculate adjusted p-values
    
     * Added p-value functionality to ldPower function;
            stepwise and likelihood ratio ordering available.
        
     * Uses a new adj.p function which, ironically, calls
            ldPower.
        
     * Edited printing and summary functions to use this
            as well.

  - Graphics
    
     * Now uses base graphics, very simple
     
     * Option to show on either z-value or b-value scale
     
     * Ability to add to existing plot

  - Conditional power
    
     * Added condpower, a function to calculate simple
            conditional power
