These methods initiate `transfer` call on internal
balance method that have Fixed12 precision. With this
limit it will not overflow JSON integer bound 2**53-1
Actual limit is 9007, but it was floored.

Since all contract methods have separated function,
method descriptions were moved from global comment
section to the function definitions (go-way).

In neo-go v0.91.0 manifest file should contain info
about all contract methods. To do that neo-go compiler
uses public function defined in contract file. This
commit splits entire Main function into smaller
independent contract methods.

New methods allow to bind and unbind public keys
with the owner, therefore the user can store and
access data with the key, that does not related
to the wallet.
There was a bit of confusion between contract deploying
and calling "Deploy" method. Also new "Init" method
uses generic setter to initialize contract storage.
Cheque is widely used in neofs as a definition
of structure that connected with configuration
changing or asset withdraw. This name is used
to avoid confusion with 'check' with
verification meaning.
As the user can invoke several deposit or withdraw calls
inner ring nodes should be able to differ them even if they
have the same arguments. To do that neofs-contract notifies
about tx hash, which can be used as unique identifier of
withdraw or deposit operation.
Withdraw operation works a bit different with neo:morph.
User calls "Deposit" and "Withdraw" methods that produce
notifications for the inner ring nodes.
"Deposit" method does not produce feedback, but "Withdraw"
does. Inner ring nodes check if user eligible to withdraw
assets. If so, nodes invoke "Cheque" method. This method
collects invocations from inner ring nods. When there are
2/3n + 1 invocations, smart-contract transfers assets back
to the user and produces notifications.
Inner ring nodes do not collect signatures for the cheque now.
Instead they invoke "InnerRingUpdate" method and smart-contract
checks if method was called from inner ring node. Then it
accepts cheque if there were 2/3n+1 invokes.
With neo:morph environment, there will be no direct communication
between inner ring nodes and storage nodes. neo:morph smart-contracts
will identify inner ring nodes by their signatures.
Inner ring nodes check their presence in inner ring list during
startup. "IsInnerRing" method allows to check presence efficiently
by calling this method.
