Update API for working groups to contain data for membership fees
In the organization data that is retrieved there is no way to query for the membership fees of a given level. To do this, we need to include data about fees for different aggregate revenue and employee counts. We will also need to include the currency used for the levels to make sure the most accurate accounting of fees is done. A way of retrieving the exchange rate for currencies to make sure up to date rates are used will also be needed
To make this as consistent as possible, we will need to update the front end to ensure that we ask for a single form of currency to reduce conversion errors where possible. There will need to be validation to attempt to normalize content entered into these fields as well since there are many formats to enter currency that could cause issues when attempting to match values.
