BlitzUtility is aimed at extending Blitz beyond it's initial capabilities and is a sub-project of BlitzExtensions.
All functions assume that you are passing valid parameters and do no extra checking to reduce performance impact.
# Functionality
## Containers
### List
An element-based method of creating a List in Blitz, works by creating a clone of the original Type and inserting the elements into the new flow.
* List% = BU_List_Create(TypeObject*)
Creates a new list from an existing object, using it as a way of accessing the currently selected List entry.
* BU_List_Destroy(List%)
Destroys an existing List, returning it's objects into the original type.
* Sucess% = BU_List_First(List%)
Tries to selects the first object in a List, returning false if it failed.
* Sucess% = BU_List_Last(List%)
Tries to selects the last object in a List, returning false if it failed.
* Sucess% = BU_List_Previous(List%)
Tries to selects the previous object from the currently selected one, returning false if it failed.
* Sucess% = BU_List_Next(List%)
Tries to selects the next object from the currently selected one, returning false if it failed.
* Success% = BU_List_Before(List%, TypeObject * )
Tries to select the element before the given object, returning false if it failed.
* Success% = BU_List_After(List%, TypeObject * )
Tries to select the element After the given object, returning false if it failed.
* BU_List_Insert(List%, TypeObject * )
Inserts an object at the end of the given list.
* BU_List_InsertEx(List%, TypeObject * , OtherObject*)
Inserts an object after the given other object.
* BU_List_Remove(List%, TypeObject * )
Removes an object from a list, returning it to the original type.
### Type List
A type-based method of creating Lists in Blitz, works by modifying the base Type.
* List% = BU_TypeList_Create(TypeObject*)
Creates a new list from an existing object, immediately removing it from the original type and inserting it into it's own list.
* BU_TypeList_Destroy(List%)
Destroy an existing list, returning the objects into the flow of the base type.
* BU_TypeList_Activate(List%)
Activates the list, making elements inside it available for use.
* BU_TypeList_Deactivate(List%)
Deactivates the list, restoring the flow of elements to before activation.
