Performs multiple call traces on top of the same block. Allows to trace dependent transactions.
Parameters
Params - a string array containing (required):
Array - List of trace calls with the type of trace, one or more of: "vmTrace", "trace", "stateDiff".
QUANTITY|TAG(hex string|string, optional) - Integer block number in hex string format, or the string "latest", "earliest" or "pending", see the default block parameter​
Returns
Array - Array of the given transactions' traces. 
trace(array).  Array of the given transactions’ traces.
action(object). DATA - Transaction details.
callType(string). type of method, such as call or create.
from(hex string). DATA, 20 Bytes - address of the sender.
to(hex string). DATA, 20 Bytes - address of the receiver.
gas(hex string) . QUANTITY - the amount of gas used by transaction.
input(hex string). DATA - the data send along with the transaction.
value(hex string). QUANTITY - value transferred in Wei.
result(object). DATA - Transaction result.
gasUsed(hex string) . QUANTITY - the amount of gas used by transaction.
output(hex string). DATA - Return value of the contract call. Contains only the actual value sent by a RETURN operation. If a RETURN was not executed, the output is empty bytes.
subTraces(hex string). - Traces of contract calls made by the transaction.
traceAddress(Array). - Tree list address of where the call occurred, address of the parents, and order of the current sub call.
type(string). type of method, such as call or create.
