Added expenses and their relationship to needs.
Started two functions to get total needed and total contributed from a specific need.
Merged in changes from develop that came from the contributors branch.
Added the controller methods for expenses.
Started changing the routes to work with the nested resource switchup.
Fixed last commit by adding the files I thought were added.
Changed the .gitignore back again. It seems there is no hope to get this rebase working.
Updated spacing again.
Expenses are now working and can only be managed by the appropriate people. They show properly in the show page but not elsewhere.
