Create and send a Bitcoin transaction using the BlockCypher Transaction API
# In this example we're sending some test bitcoins from an address we control to a brand new test
# address. We'll be sending the coins using the following address, public and private keys (please
# don't abuse).
# address : mtWg6ccLiZWw2Et7E5UqmHsYgrAi5wqiov
# public : 03bb318b00de944086fad67ab78a832eb1bf26916053ecd3b14a3f48f9fbe0821f
# private : 1af97b1f428ac89b7d35323ea7a68aba8cad178a04eddbbf591f65671bae48a2
