 The method `near(zipcode|coordinates, distance[, options])` takes 2 to 3 arguments.
 
-* First is the zipcode or geo-coordinates (long/lat) to search around
-* Second is the distance (in meters) to search within
-* Third is an optional object with the following attributes:
-  * `datafile`: name for the CSV file containing zipcodes coordinates. By default it looks for a file `zipcodes.csv` in the same folder
-  * `zipcode`: name of the column in the CSV file containing the zipcode. By default it is `Zipcode`
-  * `long`: name of the column in the CSV file containing the zipcode longitude. By default it is `Long`
-  * `lat`: name of the column in the CSV file containing the zipcode latitude. By default it is 'Lat'
