StartDegree -- Option to specify the first homological degree processed by an iterative DG construction

Several routines in this package build DG algebras one homological degree at a time, starting from degree StartDegree and incrementing up to an appropriate endpoint. Raising StartDegree can be useful when a partial acyclic closure has already been cached and you wish to continue the construction from where it left off. The default value is 1.

Functions with optional argument named StartDegree:

• acyclicClosure(...,StartDegree=>...) -- Option to specify the degree to start computing the acyclic closure.
• getGenerators(...,StartDegree=>...) -- First homological degree in which to search for new algebra generators
• killCycles(...,StartDegree=>...) -- First homological degree from which killCycles begins searching for cycles
• minimalModel(...,StartDegree=>...) -- see minimalModel -- Build the minimal DG algebra resolution of a quotient ring
• minimalSemifreeResolution(...,StartDegree=>...) -- Option to specify the degree at which minimalSemifreeResolution starts killing cycles
• semifreeResolution(...,StartDegree=>...) -- Option to specify the degree at which semifreeResolution starts killing cycles
