* @param to the name or id of the account receiving the funds
* @param issuer the name or id of the asset issuer
* @param amount the amount to send (in nominal units -- to send half of a BTS, specify 0.5)
* @param asset_symbol the symbol or id of the asset to send
* @param memo a memo to attach to the transaction. The memo will be encrypted in the
* transaction and readable for the receiver. There is no length limit
* other than the limit imposed by maximum transaction size, but transaction
* increase with transaction size
* @param broadcast true to broadcast the transaction on the network
* @returns the signed transaction transferring funds
