## The traceTransaction debugging method will attempt to run the transaction in the exact
## same manner as it was executed on the network. It will replay any transaction that may
## have been executed prior to this one before it will finally attempt to execute the
## transaction that corresponds to the given hash.
##
## In addition to the hash of the transaction you may give it a secondary optional argument,
## which specifies the options for this specific call. The possible options are:
##
## * disableStorage: BOOL. Setting this to true will disable storage capture (default = false).
## * disableMemory: BOOL. Setting this to true will disable memory capture (default = false).
## * disableStack: BOOL. Setting this to true will disable stack capture (default = false).
## * disableState: BOOL. Setting this to true will disable state trie capture (default = false).
