Mark Beamer Jr 8100010220 code cleanup
-Added travis support
-updated travis to analyze code beneath the root.
-refactored upload.go to fix travis errors.
-gocyclo should ignore test files. $GOFILES needed to be adjusted.
-fix rows.Close() ignoring error. Created func to handle so defer can be used when needed also.
-fixed ignored errors.
-fixed unit test that was not passing correctly to anonymous function.
-fixed govet error for passing param inside go func.
-removed returned error, in favor of logging instead.
-added error logging for ignored error.
-fixed potential race conditions.
-removed unused append
-fixed time usage to align with go standards.
-removed unused variables
-made changes for code review.
-code comments for exported functions.
-Documented bitmap.go and insert into contact list.
-Documented dht, message, bootstrap
-Fixed comment typos
-Documented message,node, routing_table, testing in DHT package.
-Documented server, client, prism, server and shared in peer and reflector packages.
-Documented the stores in Store package.
-made defer adjustments inline and deleted the separate function.
-adjusted method in upload to take the only parameter it requires.
