- uniq() : creates an IndirectList with duplicated entries
filtered out
- subset() : creates an IndirectList with positions that satisfy
a condition predicate.
- subset_if() : creates an IndirectList with values that satisfy a
given predicate.
An indirect subset will be cheaper than creating a subset copy
of the original data, and also allows modification.
STYLE: combine UIndirectList.H into UIndirectList.H (reduce file clutter)
- improve functional compatibility with DynList (remove methods)
* eg, remove an element from any position in a DynamicList
* reduce the number of template parameters
* remove/subset regions of DynamicList
- propagate Swap template specializations for lists, hashtables
- move construct/assignment to various containers.
- add find/found methods for FixedList and UList for a more succinct
(and clearer?) usage than the equivalent global findIndex() function.
- simplify List_FOR_ALL loops
