#'Functional Size with Bootstrapped Confidence Intervals
#'
#'This function is a master function, calling other functions it needs,
#'and reporting results in some detail
#'
#'@param lineup_vec A numeric vector of lineup choices
#'@param target_pos A scalar, representing target position in lineup. Must be declared by user
#'@param R Number of bootstrap samples. Defaults to 1000
#'@param k Number of members in lineup. Must be specified by user (scalar).
