# This code is for extension of DataFrames.
# By the extension, fingerprint can be loaded via string. 
# Each fingerprint is a set of the binary integers in python. 
# However, it can be not be loaded directly in Julia, which directly 
# trainslate a binary integer string to big interger. It is automatic even if 
# quoto mark is aded. Hence, "Julia" is added on a binary string as a prefix. 
# By doing that, Julia can read them as a character string rather than a big integer value. 


# bs2ba() transform binary string to binary array.
