 If you would like to contribute some code- awesome!  I just ask that you make it conform to the coding conventions already set in here, and to add a couple of tests for your new code to fmdb.m.  And of course, the code should be of general use to more than just a couple of folks.  Send your patches to gus@flyingmeat.com.

     Added `NS_FORMAT_FUNCTION` qualifier to `executeQueryWithFormat` and `executeUpdateWithFormat`. These methods take format strings and variable number of arguments and you will now receive compiler warnings if the types of your parameters dont match the format string.
