first version of Gauth that is ready for anybody else
rewhacked the filesystem to reflect new package structure
had a spurious copy of seven5 in the source
updated imports to point to github so they work out of the box
updated a bunch of things to be up to the new pub layout standard and the M2 spec
got most of the port to web components working
improved example1 to bring it inline with current seven5 and dart M2
