Mobile SDK Batch Requests

Symbiosis Mobile SDK for Symbiosis protocol V1: Batch Requests

Design
Json-RPC allows packing several requests into one called a batch request.
Symbiosis Mobile SDK supports batch requests: there is a "builder" and an "executor" for each request. 
For example, 
moko-web3 has Web3Requests, and
The classes defined in the contracts package have fun something() in addition to fun somethingRequest() method.
For example: balanceOf() → balanceOfRequest(), reserves() → reservesRequest()
Important: there is an exception for write transactions. A write transaction should contain a correct, unique nonce. Therefore, you can send only one write transaction at a time.
Use
There is an example of how to use a batch request: 
val (uniBalance, daiBalance, ethBalance) = client.executeBatch(
    uniToken.balanceOfRequest(address),
    daiToken.balanceOfRequest(address),
    Web3Requests.getNativeBalance(address)
)
It shows that calls can be repetitive within one batch request. 
Limitations: within one batch request, you can work with one blockchain.
