Namespace: Deedle.Indices.Linear

A virtual index that represents a subrange of a specified index. This is useful for windowing operations where we do not want to allocate a new index for each window. This index can be cheaply constructed and it implements many of the standard functions without actually allocating the index (e.g. KeyCount, KeyAt, IsEmpty). For more complex index manipulations (including lookup), an actual index is constructed lazily.
