TODO

[_] Refactor errors to not use execution results for success
Fix memory problems on the return (when size is 0)
Refactor create and create 2, also get create to work
Fix calling costs and split up function
Fix Calldata load, Code load etc.
[_] Do general clean up
- Better error handling
- Refactor where macros and functions are
- Remove lambdas
- Move costs into a config
- Separate gas cost logic from main logic
Get Memory Buffer tests to work
- Check CODECOPY
- Check CALLDATACOPY
- Check initial costs
Make gas refunds handle reverts
[_] Change to H256 instead of U256 where needed (and H160)
[_] Only pass JSON once in tests, (maybe pass in the proc macro and then directly insert in the code)
Replace macro with method in decoder?
Replace closure with macro
Move entire decode step into inline function
[?] Restructure code into a folder system
More specific error handling
Create better gas tracking, (esplet success = 's: { // Try to send value two times. for _ in 0..2 { value = match send(value) { Ok(()) => break 's true, Err(SendError(value)) => value, } } false };

ecially for memory) - [x] Created gas tracker - [x] Apply gas tracker to memory operations - [x] Apply gas tracker to all other operations

[?] Implement Reverts if failure (especially in calls)
[_] Check the failure behavior of every instruction
Create a helper proc macro that creates a map from opcode to string value
[_] Remove assembler? Maybe find an assembler crate
[_] Fix test proc to auto detect if a file or folder and auto search sub directories
[_] Allow specifying of a specific test in a file
[?] Get all arithmetic tests to pass
[?] Fix SSTORE and CALL costs (still not very clear)
[?] Implement better system for reverts etc.
Check against official ethereum vm logs to debug
Fix memory access costs, need to consolidate all memory accesses to a single memory
Fix debug code to be prettier
Original Storage value, (modify gas usage to support this)
Apply gas usage
Get the root hash to work on a test, require making sure gas usage is applied and that the hash is calculated correctly
Restructure the way in which a transaction is called on the EVM
Allow reverting of storage (can be done inefficiently for now)
Implement hash of state for mock runtime
Finish implementing call, (without gas calculations)
[N] Define tests for instructions not using runtime
- Create Proc macro to define tests in json
Add variable gas calculations
Create test implementing of Runtime
Revert only current context, (not also if a call fails)
Handle not enough values on stack
[N] Define test for instructions using runtime
[_] Implement delegate call and create 2
[_] Implement Create
[_] Define tests for mem and stack
