semifreeResolution(...,StartDegree=>...) -- Option to specify the degree at which semifreeResolution starts killing cycles

Description

Controls the first hom-degree at which semifreeResolution attempts to kill homology. Hom-degrees strictly below StartDegree are populated only by the initial free cover and the adjoinment of presentation relations at hom-degree 1. The default value is 1.
