## Print text on center of console
```python
import ezztui
ezztui.center_message("Hello World!") # prints "Hello World!" on the center of the console
ezztui.center_multiline(["Hello", "multiline", "world!"]) # prints "Hello" on the center of the console, then "multiline" on the next line, then "world!" on the next line
```
## Clear console
```python
import ezztui
ezztui.cls() # clears the console with a os.system command
ezztui.softcls() # clears the console with a multiple newline
```
## Menu
### Usage
```python
import ezztui
menu = {
'First menu':
{'Function 1': 'ezztui_return_value', # use 'return' also from 2.0.0
'Function 2': 'ezztui_return_value', # specify a function to be called from 4.0.0
'Function 3': 'ezztui_return_value',
'Function 4': 'ezztui_return_value',
'Function 5': 'ezztui_return_value',
'Back': 'ezztui_back_value'}, # use 'back' also from 2.0.0
'Second menu':
{'Submenu 1': {
'Function 1': 'ezztui_return_value',
'Function 2': 'ezztui_return_value',
'Function 3': 'ezztui_return_value',
'Function 4': 'ezztui_return_value',
'Function 5': 'ezztui_return_value',
'Back': 'ezztui_back_value'},
'Submenu 2': {
'Function 1': 'ezztui_return_value',
'Function 2': 'ezztui_return_value',
'Function 3': 'ezztui_return_value',
'Function 4': 'ezztui_return_value',
'Back': 'ezztui_back_value'},
'Submenu 3': {
'Function 1': 'ezztui_return_value',
'Function 2': 'ezztui_return_value',
'Function 3': 'ezztui_return_value',
'Back': 'ezztui_back_value'},
'Submenu 4': {
'Function 1': 'ezztui_return_value',
'Function 2': 'ezztui_return_value',
'Back': 'ezztui_back_value'},
'Back': 'ezztui_back_value'},
'No submenu function': 'ezztui_return_value',
'Third menu':
{'Function 1': 'ezztui_return_value',
'Function 2': 'ezztui_return_value',

'Function 4': 'ezztui_return_value',
'Back': 'ezztui_back_value'},
'Exit':
{"Exit": 'ezztui_exit_value',
"Back": 'ezztui_back_value'} # use 'exit' also from 2.0.0
}
print(ezztui.menu(menu)) # prints the menu and returns name of function and path to it in menu,
