=head1 SYNOPSIS

#OR

use APP::REST::RestTestSuite;

# overrides the default config and log file paths

=head1 DESCRIPTION

APP::REST::RestTestSuite object is instantiated with the data in config file. 
Default config file format is defined in __DATA__ and that can be overridden
by passing the config file as an argument to the class.
Default LOG file path is the current working directory of the script which
