What are the significant changes in functionality due to this change request?

When a HERON XML script containing no <Components> node is input to the src/heron/create_componentsets_in_HERON() function, the function now adds a new <Components> node. It also prints a message stating that the addition was made. This mirrors the function's behavior when dealing with input scripts that are missing <economics> or <CashFlow> nodes.

And I believe the multi-line strings like the input in this docstring should be indented at least to the comma on the previous line (it was bothering me and might as well ask since you're already editing the file!): https://github.com/idaholab/FORCE/pull/16/files#diff-e5a05e2d7232d1a807b092ef316d5d19d9eaec4b6043a74cd4dd42512f90daa2R36
