#NAME delete_maps.php
#TYPE PHP
#USES sql_lib(authenticate tableQuery deleteMap deleteMapMarkerLink)
# html_lib(printMapCheckList printMapSelectList)
#PURPOSE To give the user a form to delete one or more maps from the database.
#USAGE delete_maps.php
#PARAMETERS
# authorized user auth_user int optional
# want list want_list int optional
# map ids map_ids list optional
# map multiple pages map_multiple_pages int optional
# function to call function_to_call string optional
# table name table_name string optional
# field list field_list list optional
# term term list optional
# mode mode list optional
# order by order_by string optional
# last record retrieved last_record_retrieved int optional
#RETURNS
# success message string if success
# error message string if error
#DATASTRUCTURES No special databastructures.
#FUNCTIONAL DESCRIPTION Authenticate the user. Then determine whether they want a list or
# select the map name of the map to delete. Get the data and delete
# the map(s)
#ASSUMPTIONS The user knows that deleteing a map will delete all the links between markers in that map.
#LIMITATIONS No way to check, besides telling the user on the form.
#COMMENTS
#PRELIMINARY DESIGN
# 1 Get Args
# 2 Authenticate
# 3 Determine if want list or not
# 4 If don't want list, give form
# 5 If don't want list, get map name and delete
# 6 If want list, give list
# 7 If want list, get list of maps and delete
