lots of stuff in here - Githubissues

Before merging, I'd like to

[ ] get client to compile with an example that uses the bank module
[ ] consider stuff in #58 to see if we can make the genesis config less configy...

This is the current testnet_genesis function

pub fn testnet_genesis(
    initial_authorities: Vec<(AuraId, GrandpaId)>,
    root_key: AccountId,
    endowed_accounts: Vec<AccountId>,
    org_membership: Option<Vec<(u32, AccountId, bool)>>,
    flat_share_supervisors: Option<Vec<(u32, u32, AccountId)>>,
    flat_share_membership: Option<Vec<(u32, u32, AccountId, bool)>>,
    weighted_share_supervisors: Option<Vec<(u32, u32, AccountId)>>,
    weighted_share_membership: Option<Vec<(u32, u32, AccountId, Shares)>>,
    first_org_value_constitution: Vec<u8>,
    first_org_flat_membership: Vec<AccountId>,
    _enable_println: bool,
) -> GenesisConfig {
    GenesisConfig {
        frame_system: Some(SystemConfig {
            code: WASM_BINARY.to_vec(),
            changes_trie_config: Default::default(),
        }),
        pallet_balances: Some(BalancesConfig {
            balances: endowed_accounts
                .iter()
                .cloned()
                .map(|k| (k, 1 << 60))
                .collect(),
        }),
        pallet_indices: Some(IndicesConfig { indices: vec![] }),
        membership: Some(MembershipConfig {
            omnipotent_key: root_key.clone(),
            membership: org_membership,
        }),
        shares_membership: Some(SharesMembershipConfig {
            share_supervisors: flat_share_supervisors,
            shareholder_membership: flat_share_membership,
        }),
        shares_atomic: Some(SharesAtomicConfig {
            share_supervisors: weighted_share_supervisors,
            shareholder_membership: weighted_share_membership,
        }),
        bank: Some(BankConfig {
            first_organization_supervisor: root_key.clone(),
            first_organization_value_constitution: first_org_value_constitution,
            first_organization_flat_membership: first_org_flat_membership,
        }),
        pallet_aura: Some(AuraConfig {
            authorities: initial_authorities.iter().map(|x| (x.0.clone())).collect(),
        }),
        pallet_grandpa: Some(GrandpaConfig {
            authorities: initial_authorities
                .iter()
                .map(|x| (x.1.clone(), 1))
                .collect(),
        }),
        pallet_sudo: Some(SudoConfig { key: root_key }),
    }
}

and I know it can be made cleaner with the builder pattern demonstrated in that other PR...
