.send_tiger_url

An internal function for sending http requests to
the US Census Bureau TIGER api via httr::GET() function.

internal

The key function 'get_vintage_data()' returns a dataframe and is
the window into the Census Bureau API requiring just a dataset name,
vintage(year), and vector of variable names for survey estimates/percentages.
Other functions assist in searching for available datasets, geographies,
group/variable concepts of interest.  Also provided are functions to access
and layer (via standard piping) displayable geometries for the US, states,
counties, blocks/tracts, roads, landmarks, places, and bodies of water.
Joining survey data with many of the geometry functions is built-in to
produce choropleth maps.
