UPDATE: move literal values to constants and referenced from getters (so they could be changed in subsequent projects)

Currently the "bootstrap.html" and "www" folders are referenced by literals in private methods.

By moving those literals to constants and then referencing those values through getters, they could be changed in other projects with minimal impact.
FIX: use the getter instead of the literal for the www folder.
