FWIW: In my experience I need to use strfind usually on text that is
a string. Normally this is a part of parsing of some external data file
with a not well-defined structure.
The text is a cellstr usually when there is a known or well-defined
structure and one can use this knowledge to optimise the search.
So my vote would go for the Implementation 4 -- I would like to have
the best performance for the most common case rather than the best
performance in the most general case.
