Changes to Chado Installation that Karl O. Pinc suggested

http://gmod.827538.n3.nabble.com/RFC-Chado-relase-v1-3-tp4048655p4048701.html

• Do not delete tables before installing. (If the table already exists the transaction should roll back.)
• Do not be so chatty, display only warnings and errors, not informational messages.
• I would like to have it be possible to install Chado into it's own schema. The first step for this is to get rid of the multiple schemas that Chado currently uses.
• I would like to see Chado be able to be installed modularly. At present this is rather-to-very difficult. (At least it's difficult if you want only Chado. I don't know the process if Tripal is involved.) See email link for ideas on how to do this.
• In a follow up email, Siddhartha Basu suggested releasing just the DDL without the software.
