added the basic range slider in form of HTML tag, since the rails range_tag_field was throwing errors
had to give spaces for the attributes of range tag, otherwise it was including the comma into the property of each attribute
no commas are needed in the input tag, defined the step value
I think, I figured out how to use the range_field_tag...commented out the HTML input tag
added all needed properties for the range_field_tag for now
deleted the commented out HTML input tag
added a datalist to the range slider with options
added and output view for user selection of distance
deleted commented out lines of code
the distance range variable passed to google will depent on the range selection of the user
added in the venue controller to the search param the distance
