* Decoupling op logic and gas - introduce gasometer, rework opcode declaration
* Remove gas constants for gas opcode computation
* Remove gas constants for precompiled contracts
* make vm_types compile
* Make opcode, call and computation compile
* Distinguish between dynamic and complex gas costs, fix arithmetic
* Fix context and sha3
* update memory and storage ops
* Log opcode uses memory expansion code
* update/stub system_ops with gas costs
* Make test compile. Deactivate stub test_vm
* all tests compiles, opcode fails due to https://github.com/nim-lang/Nim/issues/8007 (const object variant in tables reset at runtime)
* Create an enum without holes - workaround: https://github.com/nim-lang/Nim/issues/8007
* Use arrays instead of tables for GasCosts, remove some unused imports - passing all basic tests!
* Make test_vm_json compile
* Fix test_vm_json - workaround https://github.com/nim-lang/Nim/issues/8015
* fix memory expansion cost bug
* Remove leftover special handling from before GckMemExpansion
* cleanup outdated comment, better align =
* Fix sha3 gas cost not taking memory expansion into account
* Improve gas error reporting of test_vm_json
* Fix gas computation regression due to mem expansion
* mass replace for memExpansion->RequestedMemSize was too eager
* fix log gas cost (no tests :/)
* missed a static FeeSchedule
* static as expression is fickle
* Start by renaming the fork by chronological order
* initial commit - groundwork: support different gasCosts depending on VMs
* Running VMTests with new gas config - only push32AndSuicide changed
* Introduce newNimbusVM that (temporarily) abstract over Frontier and Tangerine VM creation
* Fix Gas - push32AndSuicide repassing and expXY_success passing - fixes#34
* case sensitive imports (thank you auto-completion) fix Travis on Linux
* Add pre and post EIP-150 tests
* Nimify gas identifiers that supports multiple forks
* Stack underflow: Add failing test to catch #31
* ensurePop, use proc instead of template + add comment for future refactoring of popInternal
* Check stack underflows before popping values
* run json tests again
