Volunteer Database Client

A database systems assignment: a Java client over JDBC that queries a volunteer-project schema. The assignment specification is preserved in the method documentation - list projects with their host organizations, find projects by start date, search by category and by keyword, change a time slot duration, sign a volunteer up for a slot, and add a project.

Attention: Archived and honestly incomplete. The main Project3 class is the assignment skeleton with the method bodies unfilled; the working prepared-statement code lives in the separate TEST class. The file also carries a hardcoded school database login that should be removed from the repo history if that account still exists.
