C# Class Summer.Batch.Core.Partition.Support.SimpleStepExecutionSplitter

Generic implementation of IStepExecutionSplitter that delegates to a IPartitioner to generate ExecutionContext instances. Takes care of restartability and identifying the step executions from previous runs of the same job. The generated StepExecution instances have names that identify them uniquely in the partition. The name is constructed from a base (name of the target step) plus a suffix taken from the IPartitioner identifiers, separated by a colon, e.g. {step1:partition0, step1:partition1, ...}.
