/*
MicroDAO V0.0.2 - <me@thorsten-zoerner.com>
===========================================================
Simplified DAO allowing to do initial funding.
- Funders are able to specify how long to keep funds in.
- If funding is not closed by this time fundes returned
- Close funding is a manual taken by the director
Single Director
- Has the possibility to file SpendingRequest
- allowed to change fundamental parameters
- allowed to move directorship forward
- deadman switch prevents lost DAO.
Each Spending needs to be approved by share holders (Vote)
- spendings have a time to vote
- spendings require to be executed in a given number of days
- Checked for recursive withdraw bug (DAO Hack)
