multi_span

Header: multi_span.h

This class implements a span of a range of spans.
Allows implementation of Scatter/Gather to multiple buffers or ports.
Iterating through the multi_span will iterate through the collection of spans consecutively.
The list of spans must be in a contiguous list, such as an array or vector.

etl::multi_span<typename T>

Where T is the element type of the spans.
