title: displaying .json files in leaflet
body: <p>I have 5 .shp files from <a href="http://websoilsurvey.sc.egov.usda.gov/App/WebSoilSurvey.aspx" rel="nofollow">http://websoilsurvey.sc.egov.usda.gov/App/WebSoilSurvey.aspx</a>
  I would like to overlay these .shp files onto my existing tile photos in leaflet.</p>
  
  <p>I have converted the 5 .shp files to .json using ogr2ogr, but I do not know how add all of these .json files as overlay to my existing tilings.  Any help would be appreciated, thanks.</p>
