Un-assign loan officer from loan account

Hello Keith,

in my local machine commit message is wrong, by mistake executed commit command from history and pushed to origin. Is this a problem ?

Regarding service functionality
1) Service "unassign" the loan officer from loan just by accepting loanid and unassigned-Date
2) Add end_date in m_loan_officer_assignment_history table for this loan's latest entry with no end_date is updated by unassigned-Date
3) If you try to unassign loan officer to loan with no loan officer then it through a exception 

I have question,
unassigned-Date parameter is validated only for not null. Does service need to validate it for future date / past date ?

And is there need of bulk-unassign feature. 

Now I will start working on UI for getting unassign button.

Thanks
