/**

 * 
 * This class will allow support for user's passing in passwords through a
 * variety of ways. Current supported options for passwords include standard
 * password input (pass), an environment variable (env), a file containing the
 * password text (file), a properties file containing the password associated
 * with a specific key (propfile), and the user being prompted to enter the
 * password at command line (stdin). <br/>
 * <br/>
 * Required notation for specifying varying inputs are:
 * <ul>
 * <li><b>pass</b>:<password></li>
 * <li><b>env</b>:<variable containing the password></li>
 * <li><b>file</b>:<local file containing the password></li>
 * <li><b>propfile</b>:<local properties file containing the
 * password><b>:</b><property file key></li>
 * <li><b>stdin</b></li>
