/**
 * A column width calculator that calculates column width for a specific column or a group of columns.
 * It also provide the minimum required row width for the total columns added up to that point.
 *
 * The `DynamicColumnWidthLogic` takes into account real-time DOM measurements (especially box-model metadata), hence "dynamic".
 * It performs the calculation based on `PblColumn` and actual DOM size metadata.
 *
 * The `DynamicColumnWidthLogic` has 3 responsibilities:
 *
 * - It is responsible for enforcing the `maxWidth` boundary constraint for every column it processes by calculating the actual width
 * of a column and calling `PblColumn.checkMaxWidthLock` to verify if max width lock has changed due to the new actual width.
 *
 * - It calculates the absolute width for a group of columns, so `PblCdkVirtualScrollViewportComponentGroupColumn` can have an exact size that wraps it's children.
 *
 * - It calculates the `minimumRowWidth`, which represents the minimum width required width of the row, i.e. table.
 *
 * > Note that an instance of `DynamicColumnWidthLogic` represents a one-time pass for all columns, for every run a new instance is required.
