KP: Working on PHP retrieval page, getinfo performs mysql query and returns
json object.  index.php populates a dropdown from mysql, then uses ajax
call against getinfo.php.
This will all need to cleaned up, I don't like how index.php is formatted
right now

Just some organization
KP - Updated njtrends.js to output data as a table. Ajax call reads
from getinfo.php and outputs to page in a semi readable format.
Updated index.php to order the dropdown to make it easier to find
the trainID we are looking for

KP: Improved the SQL query to group by date so we only see one
entry per day.

Merge branch 'phpretrieve'
