* Changed the name of the file from tremor to telaria (Company was renamed) and updated the documentation

* - Added back the documentation for the older (prebid 0.x) adapter

* Removed the parameter section from the doc because they can change. Pubs using our adapter can login to our console to get a list of params.

made the reference to tremor a link, don't need the 1.0 note in the description -- moving to the prebid_1_0_supported flag

* Updated to set gdpr_supported: true.

* added a telaria prebid example.

* - Added a section about SupplyChain Object

* updated the documentation and added the different ways of passing the schain object
