Allow for comments in a cassandra-cli file

I use the cassandra-cli to create schemas, update schemas, and make other calls to interrogate keyspaces and columns. I load pre-written statements from files using the -f option, example: "bin/cassandra-cli -host localhost -port 9160 -f mystatements.txt". It would be useful if I could comment my statement files with comments similar to how you can comment script and C++/Java code.

Example contents of "mystatements.txt" file:
update column family users // This is my column which holds all my user information
with comparator = UTF8Type // My column names are all strings so I will use UTF8Type
and key_validation_class = UTF8Type // My row key values are also UTF8Type
and default_validation_class = UTF8Type // Column values will be UTF8Type
and column_metadata = [

{column_name: username, validation_class: UTF8Type}

, // This column stores the login name of the user

{column_name: realname, validation_class: UTF8Type}

];// This column stores the real world name of user
