Arguments:
1. "txid"                 (string, required) The transaction id (must be in mempool)
2. verbose                  (boolean, optional, default=false) True for a json object, false for array of transaction ids

Result (for verbose=false):
[                       (json array of strings)
  "transactionid"           (string) The transaction id of an in-mempool descendant transaction
  ,...
]

Result (for verbose=true):
{                           (json object)
  "transactionid" : {       (json object)
    "size" : n,             (numeric) virtual transaction size as defined in BIP 141. This is different from actual serialized size for witness transactions as witness data is discounted.
    "fee" : n,              (numeric) transaction fee in BTC
    "modifiedfee" : n,      (numeric) transaction fee with fee deltas used for mining priority
    "time" : n,             (numeric) local time transaction entered pool in seconds since 1 Jan 1970 GMT
    "height" : n,           (numeric) block height when transaction entered pool
    "descendantcount" : n,  (numeric) number of in-mempool descendant transactions (including this one)
    "descendantsize" : n,   (numeric) virtual transaction size of in-mempool descendants (including this one)
    "descendantfees" : n,   (numeric) modified fees (see above) of in-mempool descendants (including this one)
    "ancestorcount" : n,    (numeric) number of in-mempool ancestor transactions (including this one)
    "ancestorsize" : n,     (numeric) virtual transaction size of in-mempool ancestors (including this one)
    "ancestorfees" : n,     (numeric) modified fees (see above) of in-mempool ancestors (including this one)
    "wtxid" : hash,         (string) hash of serialized transaction, including witness data
    "depends" : [           (array) unconfirmed transactions used as inputs for this transaction
        "transactionid",    (string) parent transaction id
       ... ]
  }, ...
}
