Section: Container Classes

The container classes are type parameterized datastructures. The 
<uvm_queue #(T)> class implements a queue datastructure similar to the 
SystemVerilog queue construct. And the <uvm_pool #(KEY,T)> class implements 
a pool datastructure similar to the SystemVerilog associative array. The 
class based datastructures allow the objects to be shared by reference; 
for example, a copy of a <uvm_pool #(KEY,T)> object will copy just the class 
handle instead of the entire associative array.
