Add productcode to the FDSNWebService as a parameter.
Order FDSN methods and parameters alphabetically.
Fix typos. Explain different xml formats.
List format types after the request method section.
added div's for toggles to work
reordered initialize to remove the double call,  then added a call to _bindModelUpdate in fetchfielddata to rebind the asynchronous fields
removed display:block to allow input types to show in toggles, when asynch call fails,  added line-height:1.3 to compensate
pulled divs,  used css changes instead
Added _getFieldId to deal with spaces in fieldId's.
cleaned up _initialize, made parsedUrl a local variable,  added code to set radio buttons from the model after asynch call returns
corrected white space issues
