#' Build the Segment in Adobe Analytics
#'
#' This function combines rules, containers and/or sequences into a single JSON
#' string and can then make the post call to create the segment in Adobe Analytics
#' or return the json string for use in other api calls or for validation.
#'
#'
#' @param name This is the name of the new segment (required)
#' @param description  This is the description of the segment (required)
#' @param containers List of the container(s) that make up the segment. Containers
#' are list objects created using the [`seg_con()`] function.
#' @param rules List of the rule(s) to create a segment. Rules are list objects
#' created using the [`seg_rule()`] function.
#' @param sequences List of the rule(s) and sequence container(s) that are combined
#' to make a segment. Sequence containers are list objects created using the [`seg_seq()`] function.
#' @param context Defines the level that the segment logic should operate on.
#' Valid values are visitors, visits, and hits. See Details
#' @param conjunction This will tell how the different containers and rules should
#' be compared. Use either 'and' or 'or'.
#' @param sequence Used to define if the segment should be 'in_order' (default),
#' 'after', or 'before' the sequence of events
#' @param sequence_context Used to define the sequential items context which should
#' be below the container context. ex. if container context is visitors then the
#' sequence_context should be visits or hits
#' @param exclude Excludes the main container which will include all rules.
#' Only used when the rule arguments are used.
#' @param create_seg Used to determine if the segment should be created in the
#' report suite or if the definition should be returned to be used in a freeform
#' table API call. Default is FALSE
#' @param tagNames Apply tag names to the newly created calculated metric. Single
#' string or a vector.
#' @param internal Determines if this segment is to be available in the UI.
#' Default is FALSE, meaning the segment will not be available in the UI, nor will
#' the ID be available in the `aw_get_segments` function call.
#' @param rsid Adobe report suite ID (RSID).  If an environment variable called
#' `AW_REPORTSUITE_ID` exists in `.Renviron` or elsewhere and no `rsid` argument
#' is provided, then the `AW_REPORTSUITE_ID` value will be used. Use [aw_get_reportsuites()]
#' to get a list of available `rsid` values.
#' @param debug This enables the api call information to show in the console for
#' help with debugging issues. default is FALSE
#' @param company_id Company ID. If an environment variable called `AW_COMPANY_ID`
#' exists in `.Renviron` or elsewhere and no `company_id` argument is provided,
#' then the `AW_COMPANY_ID` value will be used. Use [get_me()] to get a list of
#' available `company_id` values.
#'
#' @details
#'
#' **Context**
#'
#' The rules in a segment have a context that specify the level of operation.
#' The context can be "visitors", "visits" or "hits."
#' As an example, let's build a segment rule where revenue is greater than 0
#' (meaning a purchase took place) and change the context to see how things change.
#' If the context is set to "visitors", the segment includes all hits from visitors
#' that have a purchase of some kind during a visit. This is useful in analyzing
#' customer behavior in visits leading up to a purchase and possibly behavior after a purchase.
#' If the context is set to "visits", the segment includes all hits from visits where
#' a purchase occurred. This is useful for seeing the behavior of a visitor in
#' immediate page views leading up to the purchase.
#' If the context is set to "hits", the segment only includes hits where a purchase
#' occurred, and no other hits. This is useful in seeing which products were most
#' popular.
#' In the above example, the context for the container listed is hits. This means
#' that the container only evaluates data at the hit level, (in contrast to visit
#' or visitor level). The rows in the container are also at the hit level.
#'
#' @return If the "create_seg" argument is set to FALSE a JSON string definition
#' will be returned. If the "create_seg" argument is set to TRUE and the segment
#' is valid it will return a data frame of the newly created segment id along
#' with some other basic meta data. If it returns an error then the error
#' response will be returned to help understand what needs to be corrected.
