Who is Bakayoko from God's Bits of Wood and what is their importance?

Bakayoko is the novel's central character, in spite of the fact that he doesn't actually appear in person until more than two thirds of the way through. In short, even while the narrative line is defined by the actions and circumstances of other characters, Bakayoko is a constant presence, undeniably a leader, and a profoundly complex human being, simultaneously idealistic and pragmatic, restrained and passionate, charismatic and reserved, personally arrogant and professionally a servant of the people.
