[Collaboa] time estimates

[Michael Fairchild]

I think this sounds great.  I am writing a timecard/estimating app for a 
boatyard now and i just have a table of timecards and a table of 
estiamate_lines.  Timecards and estimate_lines both belong to each other 
and i can get all the data i need from this.  One thing i do not have, 
but like, and may implement is the original_estimated_hours idea.  Would 
be nice to have so you could have an indicator as to how accurate your 
estimating is, and hopefully improve.    Having a table of timecards it 
is easy to create added functionality/invoices if you want later on.  
Adding billable, billed, and bill_to fields would make this pretty 
easy.  I would ignore billing in the beginning tho.
  just one way, I know there are plenty of good ways to do this.  Mine 
is only one that is working for me.
