Capped cylinder == capsule. It's what most people use, together with a 
down-sensing ray for the ground/legs collision. You allow climbing when 
the capsule doesn't touch any other geometry, and apply significant 
movement drag when it is touching other geometry.

This is such a common way of generating characters that I'm not 
surprised there aren't that many questions about it :-)
