Made a scaffold for the demo app
Reorganized the file to be able to build without bumping, and properly remove comments from the non-minified build
Three fixes, which will require a new minor version:
1)  Hash string was wiped when path fragment was at the specified root; fixed by wrapping "atRoot"
2)  Improved ".deleteHash()" API
3)  All method options that have "opts.apply" option available will have it default to true
More work on demo app
fix: "fragment" property for ".navigate()" method is now truly, and the "._navigationInProgress" property prevents infinite loops
Demo app finished!
Updated demo docs
