changed the path redirect when a user logs in so
that it takes them back to the page they were on.
changed loan requests in the seed file to make
amounts divisible by 25
added a check so that the amount funded can’t be
larger than the borrowing amount
Added a method that calculates the remaining amount
for a loan request
Added a drop down box for how much a user wants to
loan in $25 increments

If the remaining amount less than $500 then
the drop down is limited to the remaining amount
WIP
Added a new cart model and tests for it.
Refactored the cart.

Added a helper method for the cart method at the
bottom that returns @cart, or sets it up if it
doesn’t already exist

The index no longer builds the @cart variable and
now only needs to check if the cart is empty.

removed the TODO’s

changed the view to use the new method found in
the cart model
