add section title formatting, add section detailing basic club responsibilities

If they "may be assumed by any entrusted-member regardless of rank status", then who is to say that any member does not suddenly appoint themselves master of fundraising and command club monies?

Further, we define "active member" and use it throughout the constitution, but we haven't defined entrusted-member. I think the language should be consistent - if we mean *active member* here, then we should use that phrase, and if we mean *any active member, once appointed to the position, may assume a rank-holding position in the club* then we should write that and not be ho-hum about it.
