Toward a web service, the demo HTLM form now uses HTTP GET instead of POST. The tissue values no longer include spaces. The form accepts exactly one gene and at most one tissue. The CGI script now accepts only one gene and at most one tissue. The CGI still returns HTML only.
Fix template for display of plain text. Now the search for expression values of a single gene can display results as simple HTML or as a quoted comma-separated line-oriented (csv) text file. This was implemented for the web services demo but it fixes the interactive site also, on which plain text results was returning an error.
Add option to return JSON.
