CPG: Admin page language download

[michaelmarshall]

repo: cpg branch: language-lists page in app: admin

data tables we need: ethnologue, iso, glottolog

tasks:

1. add a function to pull data from hard-coded webpages to get language table data. for now it could be our server.
2. store data in the graph using the graph layer 3 table api shown here.
3. create function to read from the graph table and create/update a table for every table that exists in the graph. So if there is a 'table' node in the graph for 'ethnologue', you will create an actual table called 'ethnologue'. You'll add columns and rows based on the data stored in the graph.
4. update the /language-lists page to show the language data. wireframe is in comments
