- The value of a given amount against the CPI values for each month of the current year.

Enhancements
- Improved the `InflationCalculator` to handle edge cases more effectively.
- Added methods for current year CPI changes and historical comparisons.

Bug Fixes
- Fixed an issue where monthly CPI data was not correctly falling back to yearly averages.
- Corrected the CPI data validation process to handle missing data more gracefully.
- Resolved inconsistencies in the inflation adjustment calculations for specific years.

Usage Examples
python
from dollarwave import GUI

Run the GUI
GUI.run()


python
from dollarwave import inflation_calculator

Calculate the current year change
print(inflation_calculator.current_year_change(amount=5))

- **Easy to Use**: Provides a straightforward API for calculating inflation-adjusted values.
- **Data Validation**: Ensures the accuracy and consistency of CPI data used in calculations.

Key Features

1. **Inflation Adjustment Calculation**:
- Calculates the equivalent value of an amount of money in different years using CPI data.
- Automatically switches to yearly averages if monthly data is not available for the most recent comparison year.

2. **Data Handling and Validation**:
- Validates CPI data to ensure it meets the required criteria.

Usage Examples

Calculating Inflation-Adjusted Values

Use the `InflationCalculator` to calculate the equivalent value of money across different years:

python
from dollarwave import inflation_calculator

Calculate the adjusted value
original_amount = 1
original_year = 1970
target_year = 2024
adjusted_amount = inflation_calculator(original_amount, original_year, target_year)

Output:

$1 from 1970 is equivalent to $8.04 in 2024 dollars.
