| `condition`       | public  |           |               | The funtion which us run to check if this step can be transitioned to.
Takes lion-steps data as a first argument \`myConditionFunc(data)\`.                                                                                 |                |
| `forwardOnly`     | public  | `boolean` | `false`       | Allows transition to step only in forward direction. Skips it if transitioned back.
May be useful if the step is only showing some messages and does data loading and
then makes transition to next step automatically. |                |
| `initialStep`     | public  | `boolean` | `false`       | If set this step will be the initially enabled step
There should be only ONE intial step in each steps                                                                                                                      |                |
| `invertCondition` | public  | `boolean` | `false`       | Allows to invert condition function result.                                                                                                                                                                                     |                |
| `status`          | public  | `string`  | `'untouched'` | Step status, one of: "untouched", "entered", "left", "skipped".                                                                                                                                                                 |                |
