+
+Internal notes:
+
+This component creates two JS functions: process(), which starts the
+submission process, and start_job(), which starts the job on the
+server side.
+
+process() does the following:
+- disable the form submit button
+- for all form fields named in "fields", collect their values into an array
+- declare a callback function "myCallback"
+- pass the array and callback to start_job()
