Continuation Core and Toolboxes (COCO) Code

Adding support for discrete monitor functions and event detection

Corrected typo in Tutorial

Updated atlas tutorial to describe 'branch' optional setting.

Remove temporary UST1 solution type.

Updated tutorials for 'ep', 'coll', 'ep', and Getting Started to agree with code and demo updates to branch handling.

New demo for showing how core handles regularization of linearly dependent constraints.

Major update to branch handling for core and 'ep', 'coll', and 'po' toolboxes, including updates to all relevant demos (only CORE tutorial has been updated). In new version, branch handling depends on a 'branch' property of the 'cont' settings. This property takes three distincts values. CurveSegment and the default value are designed to ensure backward compatibility.

Updated po utilities and demos to handle tangent vectors correctly. Fixed bug in mvdP files.

Updated coll restart constructors, utilities, and demos to handle tangent vectors correctly.

Updated ep_construct_tst with event handler to store SN eigenvector also when not detected as fold point: Modified ep_read_solution accordingly. Updated constructors to properly handle tangent vector stored with solution file. Tentatively updated restart constructors to allow for a -no-pars option in the event that one wishes to reconstruct without adding continuation parameters. This is necessary if constructing multiple instances from stored solutions.
