Please, remove privacy statement of method `_OMIconData()`, like the `IconData()`.

Using out-of-class OMIconData() allows you to work dynamically with icons, for example:

• With IconData

    // This can come from a remote JSON (HTTP)!!!
    List<Map<String, dynamic>> _userButtonList = [
      {
        'icon': 0xe5ca, // Icons.check
        'txt': 'Button 1',
      },
      {
        'icon': 0xe169, // Icons.unarchive
        'txt': 'Button 2',
      },
    ];

    List _buttonListWidgets = <Widget>[];

    // Builder buttons for ListView
    Widget _buildButtonList(int icon, String txt) {
      return Container(
        height: 30,
        child: Column(
          children: <Widget>[
            Icon(IconData(icon, fontFamily: 'MaterialIcons')),
            Text(txt),
          ],
        ),
      );
    }

    // Builder the Widgets ListView
    _userButtonList.map((item) {
      _buttonListWidgets
          .add(_buildButtonList(item['icon'], item['txt']));
    }).toList();

• How I would like to have with OMIcons

    // This can come from a remote JSON (HTTP)!!!
    List<Map<String, dynamic>> _userButtonList = [
      {
        'icon': 0xe9d0, // OMIcons.check
        'txt': 'Button 1',
      },
      {
        'icon': 0xecef, // OMIcons.unsubscribe
        'txt': 'Button 2',
      },
    ];

    // ...

    // Builder buttons for ListView
    Widget _buildButtonList(int icon, String txt) {
      return Container(
        height: 30,
        child: Column(
          children: <Widget>[
            Icon(OMIconData(icon)),
            Text(txt),
          ],
        ),
      );
    }

    // ...

I'm using Material Design Icons this way, but I like the 'Outlined' icons based on the Material Design you created.

If you think this is good, I will send a PR for change this, so what do you think?
