* Avoid abbreviations
* Use `branch` as a more suggestive variable name than `ret`
* Cleanup spacing after comma
* Avoid having two index variables (`index` and `idx`)—Does this break anything?

994a42e6b1 Add getter to Vyper contract for Merkle branches 
Returns the Merkle branch for the leaf at index `index`. This getter provides
an alternative way for beacon chain proposers to access the Merkle tree of
deposits rather than being Ethereum 1.0 light clients. The method can be
called on a trusted Ethereum 1.0 archive node at specific past block numbers
to retrieve the Merkle branch needed to register a validator.

b78458bbb2 Removes naming conflict in get_shuffling. 
The variable name 'slot' in the for-loop in 'get_shuffling' conflicts with the get_shuffling argument name 'slot'. Renames 'slot' in for-loop to 'slot_num'.

c69fa9a793 Fixes typo in sorted function. 
In keeping with the rest of the code in this document we adhere to valid Python
where possible.

The custom comparator keyword argument for `sorted` is `key` so this commit
updates its usage when sorting validators by exit order.

a0e454d86c Fixes bug with Merkle proof branch selection 
This code determines the order in which the next branch element and the
current value should be hashed to produce the parent node in the Merkle tree.

The existing code fails to verify branches constructed in the standard way.

This patch fixes the spec code so that it works properly by using an appropriate
parity calculation.

Example code here to illustrate it working:

19a9582a48 Remove dangling return statement from spec function

state.

There is a dangling return statement that this commit deletes.

9a83ad7b9b Fix a type error with units of wei when determining ejection balance. 
`EJECTION_BALANCE` is in units of ETH.

`state.validator_balances[index]` is in units of Gwei.

For the ejection computation to work as desired, we need to convert the
`EJECTION_BALANCE` constant from ETH to Gwei.

457f84fa64 Change "justified hash" to "justified slot" 
There should be a correspondence here but referring to the slot is more
explicit, especially for those who are not as familiar with the
details of FFG finalization.
