// Main workflow is recording time
// We want to record the following information:
// - worker name
// - client name
// - date
// - duration
// - task description?

// for an initial proof of concept, just hard-code the worker names and client names into the script, or into an XML grammar.
// initial POC has no authorization or authentication
// Save the data to???

// Secondary workflows
// Registering a new user
// Approving a new user
// Finding your time worked 
// 

// Data Storage - use OData and Google AppEngine? Something else to learn!!
