### Basic usage of easing functions

Source: https://github.com/semitable/easing-functions/blob/master/README.md

Demonstrates how to import and use an easing function (QuadEaseInOut) to calculate an eased value over a specified duration. It shows both direct method call and object call for convenience.

```python
from easing_functions import *

# For a duration 10 you will get the relevant output from start to end
a = QuadEaseInOut(start=0, end = 3, duration = 10)
k = a.ease(4) # 4 is a number between 0 and the duration you specified
#k is the returned value from start to end (0 to 3)
k2 = a(4) # the ease object can also be called directly, like a function
```

### Plotting easing functions with Matplotlib

Source: https://github.com/semitable/easing-functions/blob/master/README.md

Illustrates how to use numpy and matplotlib to visualize different easing functions (BounceEaseInOut, BounceEaseIn, BounceEaseOut) over a range of values, providing a visual representation of their curves.

```python
import numpy as np
import matplotlib.pyplot as plt

a = BounceEaseInOut(start=3, end=1, duration=1)
b = BounceEaseIn(start=0, end=1)
c = BounceEaseOut(start=0, end=1)

x = np.arange(0, 1, 0.001)
y0 = list(map(a, x))
y1 = list(map(b, x))
y2 = list(map(c, x))

plt.plot(x,y0)
plt.plot(x,y1)
plt.plot(x,y2)
```
