Python Wrapper Properties include Java static method

[hythloda]

As a python user, I want no confusion about which method does what.

We should attach a property to every wrapper function to hold the name of the wrapped Java static method.

This will allows for no confusion for the user with the difference between lower_bin and lowerBin and having to know when to use which.

Something akin to an alias so theMethod in Java can be the_method when used from python.

This issue was highlighted with @jcferretti from the Debezium Python V2 rewrite. As there are two ways for the same task
['received_at_minute = lowerBin(received_at, minute_in_nanos)']

['received_at_minute = (DateTime)lower_bin(received_at, minute_in_nanos)']

A related but different issue is that when both Python and Java have symbols with the same name and both can be used in formula/filter evaluation.
