/* This file contains the functions to add, modify, remove, collapse and expand
categories.
void modifyCategory(int category_id, array catOptions)
- general function to modify the settings and position of a category.
- used by ManageBoards.php to change the settings of a category.
int createCategory(array catOptions)
- general function to create a new category and set its position.
- allows (almost) the same options as the modifyCat() function.
- returns the ID of the newly created category.
void deleteCategories(array categories_to_remove, moveChildrenTo = null)
- general function to delete one or more categories.
- allows to move all boards in the categories to a different category
before deleting them.
- if moveChildrenTo is set to null, all boards inside the given
categorieswill be deleted.
- deletes all information that's associated with the given categories.
- updates the statistics to reflect the new situation.
void collapseCategories(array categories, string new_status, array members = null, bool check_collapsable = true)
- collapses or expands one or more categories for one or more members.
- if members is null, the category is collapsed/expanded for all members.
- allows three changes to the status: 'expand', 'collapse' and 'toggle'.
- if check_collapsable is set, only category allowed to be collapsed,
will be collapsed.
