Documentation on region_type and region_id

[Rafnuss]

The documentation for all extract function () seems to be the same. I suggest we update it to:

#' @param species_ids A character or a vector of characters that represent the id or ids of the species. Example: observer_numbers = '10723' or observer_numbers = c('10723', '40147')
#' @param start_date A character representing the start date from which you want to query the database. It must be in the YYYY-MM-DD format. Defaults to 1 Jan,2019. Example: '2019-01-26'.
#' @param end_date A character representing the end date to which you want to query the database. It must be in the YYYY-MM-DD format. Defaults to 1 Feb, 2019. Example: '2019-02-26'.
#' @param region_type Can take one of the following types: country, province, pentad, group, qdgc. Default is 'country'
#' @param region_id Instantiation (i.e. co-defined with) `region_type`. If the `region_type` = 'country', then the `region_id` must be one of the following: 'kenya', 'southafrica', 'nigeria', 'botswana', 'namibia', 'zimbabwe', 'lesotho', 'swaziland', 'mozambique'. If `region_type` = 'province', then ... . If `region_type` = 'pentad', then  `region_id` is the pentad code (e.g. '3355_1825'). If `region_type` = 'group', then  `region_id` is the group code (e.g. 'BBD'). If `region_type` = 'qdgc', then  `region_id` is the qdgccode (e.g. '???'). Default is 'kenya'.
#' @param return_type There are two options, 'data' and 'count'. 'data' is the actual records submitted to the africa bird map. 'count' return a count of the rows. Default is 'data'

Any idea to improve?

Thanks Raf! Yeah definitely needs to improve. Especially with the examples. Could be a good project for first timers or folks just starting out.
