Use firebase for online option

[JPGarCar]

We would like to use firebase for an online version of the system. The system would have to log in or give the firebase credentials to access the "system" as a node.

No PI should be in firebase!

Firebase will also give us the option of having a reactive application. When things change on one node, all other nodes in the system receive the update!

Local changes would still be necessary in case wifi is lost. We could look into just grabbing the cache is wifi is lost and then using or moving that to a local db.

We should be able to update data from an excel sheet to firebase.
