Improving Trace storage for longer running programs #212

For long running Java programs, it is not unreasonable to assume that the number of traces and steps objects exceed the memory capacity of the system.

Currently, database insertions are batched with a preset BATCH_SIZE of 1000.

Let's look into:

Developing an algorithm to store traces more selectively
Optimizing connection pooling and batching operations
