Browse Source 
* Move `initialise_block` into `Core` trait as it is crucial calling the API functions

* Switch to first version of new runtime API implementation

* Fixes bug in tests

* Reenable asserts

* Directly use the `TestAPI` in the tests

* Start improving the api traits

* Refactoring

* Move `sr-api` into client and more refactoring

* Fixes tests

* Some documentation and cleanup

* Fixes compilation after rebase

* More refactoring and more documentation

* Makes `substrate-client` compilable on `wasm`

On `wasm` it basically just exports the runtime api stuff.

* Fixes grumbles

* Updates wasm files after rebasing the master

* Remove TODO comment

* Remove whitespaces

* Fixes after rebasing master

* Another rebase, another fix commit
