BuilderFacets.cpp

/**
 * @cite Builder Facets is a combination of Builder and Facade Pattern and is used when the object being built is highly complex and requires the use of multiple builders.
 * Aims at making the API more verbose and readable.
 *
 * @brief Builder Facets can be exemplified by a Person class that has multiple complex attributes (like address, job, family etc.).
 * Building the Person using a single builder will violate the Single Responsibilty principle as the builder will have to build all the complex attributes itself.
 * We can divide the build process into multiple steps and multiple builders.
