* Checkpoint before the weekend * Update location for SetupPostgresDB * Include first functioning tests for processing head * Fix gitignore * Test CaptureHead | Add Metrics | Handle Test Race Conditions This Commit allows us to: * Test the `CaptureHead` function. * Test parsing a single Head message. * Test a Reorg condition. * Add Metrics. This is primarily used for testing but can have future use cases. * Rearrange the test due to race conditions introduced by reusing a variable. `BeforeEach` can't be used to update `BC`. * Update and finalize testing at this stage * Update code and CI/CD * Fix lint errors * Update CICD and fail when file not found. * Update test to have failed as expected.
