Subject: Add implementations of find and find_if that take a container
X-Git-Url: http://git.tdb.fi/?p=libs%2Fcore.git;a=commitdiff_plain;h=8ac74c1f54ccedb86b4cd1544e2251682c0e95c8;hp=7ca970e5db84020e4735afccf43ede4d52ac0bf0

Add implementations of find and find_if that take a container

Rather than an iterator pair.  Searching through an entire container is
a very common use case.
