[Feature] Add 'Best Execution Price' Helper about 1 month ago

AI Summary: This issue proposes adding a new `getExecutionPrice` helper method to the `Exchange` class. Its purpose is to calculate the volume-weighted average price a user would pay to buy or sell a specified amount of shares by iterating through the order book and accounting for partial fills across multiple price levels. The core logic will reside in a new utility file.
