Description

Implemented a new internal object to read and keep in memory the full solution, with all its files.

Added solution show command that displays solution's elements: for now, list of files with annotation of their contents (e.g., knowledge vs. object, object type, etc.)

Added support for solution fork from a local directory, as this helps primers/tutorials/workshops and works around the restricted ability to download solutions from other tenants.

Modified the fork capability to not just do global replace (which can inadvertently replace more than necessary and break a solution); instead, it ensures that only values are changed (never keys) and only on word boundary. Additional exceptions are handled, such as renaming the namespace file (which is usually named after the solution name).

Retained the old fork capability for backward compatibility, under a --legacy-replace flag, in case the new algorithm doesn't take care of some cases that are covered in tutorials and workshops.
