This is a subclass of a UITableViewController that allows for expandable/collapsable sections.
To use it, simply import the SRExpandableTableViewController.h and SRExpandableTableViewController.m
files into your xCode project, create a UITableViewController and make it a subclass of the
SRExpandableTableViewController class. Initlialize the datasource with the
-(void)setSRExpandableTableViewControllerWithContent:(NSArray *)contentArray andSectionLabels:(NSArray *)labelsArray;
method and that's it!
Note: I did utlize some QuartzCore stuff in the class so be sure to link the QuartzCore framework to your project.
