## In addition to the hash of the transaction you may give it a secondary optional argument,

##
## * 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).
