 /**

  * Property editor to assist with the setup of a {@link UserMap}.<p>The format of entries should be:</p>

  *  <p><code> username=password,grantedAuthority[,grantedAuthority][,enabled|disabled] </code></p>

  *  <p>The <code>password</code> must always be the first entry after the equals. The <code>enabled</code> or

  * <code>disabled</code> keyword can appear anywhere (apart from the first entry reserved for the password). If

  * neither <code>enabled</code> or <code>disabled</code> appear, the default is <code>enabled</code>. At least one

  * granted authority must be listed.</p>

  *  <p>The <code>username</code> represents the key and duplicates are handled the same was as duplicates would be

  * in Java <code>Properties</code> files.</p>

  *  <p>If the above requirements are not met, the invalid entry will be silently ignored.</p>

  *  <p>This editor always assumes each entry has a non-expired account and non-expired credentials. However, it

  * does honour the user enabled/disabled flag as described above.</p>
