* fix: Add assertions to prevent excess votes and computation, and to end council seat election when no empty seats
* Add assertion to prevent a vote from voters that provide a list of votes that exceeds the desired seats length, since otherise an attacker may be able to submit a very long list of `votes` that far exceeds the amount of candidates and waste more computation than a reasonable voting bond would cover. Added additional associated test that may be run with `cargo test -p srml-council`
* Add assertion so expired council seats are not up for election when desired seat count changes during the voting period such that there are no longer any empty seats
* Update comment to refer to `reporter` instead of `who` (target of inactivity), since the origin is the `reporter`
* Update commment to refer more specifically to how many vote indexes, since `InactiveGracePeriod` is measured in vote indexes
* Update comment for `ApprovalsOf` since previously the comment was a duplicate of the comment for `LastActiveOf`'s
* Create variable to refer to `retaining_seats` to improve readability

* WIP - length votes should be less than length candidates. pushing changes for reference so can fix
* fix: Amount of candidate approval votes cannot exceed candidates amount. Candidates amount must be over zero.
* Fix so that amount of candidate approval votes cannot exceed amount of candidates (instead of desired seats)
* Add assertion to `set_approvals` such that amount of candidates to receive approval votes must be greater than zero. Add associated test
* fix: Remove assertion preventing votes when empty seats is 0
* review-fix: Replace with is_zero and add corresponding test
* Update seats.rs
* Update seats.rs
* Update SRML Assets: add total supply query, refactor with specific unit tests, update assertions
* Add feature and tests to allow querying total supply
* Add assertion and tests to ensure that transfer amount is greater than or equal to one unit
* Replace broad `it_works` function test with various specific unit tests
* Fix `destroy` function by moving assertion before the action
* Fix typos `Transfered` should be `Transferred`, `requried` should be `required`
* Reference: https://hackmd.io/nr6kPD2sR4urmljtvHs0CQ?view#Assets-Module
* refactor: Order imports alphabetically
* review-fix: Replace non-zero check with shorter equivalent
* review-fix: Restore order of non-zero assertion and destroy account
* Update lib.rs
Fixes ordering of command-line arguments. `substrate --help` shows usage as substrate `[FLAGS] [OPTIONS] [SUBCOMMAND]`, where `--chain=staging` is one of the possible OPTIONS, and `build-spec` is a possible SUBCOMMAND.
The ordering should be `substrate --chain=staging build-spec` instead.
