(Java SDK) Import User with SHA-1 Password into Stormpath

pwd-import-java.java

"""
    password-import.java
    ~~~~~~~~~
    A super basic script that shows how to import a user with a freshly SHA-1 hashed password into Stormpath 
    and authenticate him using the Java SDK (version 1.5.5): https://github.com/stormpath/stormpath-sdk-java
    
    NOTE: You will need to add the apache commons codec jar (version 1.10) to your project in order to use DigestUtils
