go-mutesting

• Go module aware
• Documentation for the expression/comparison mutator

Changes from 1.0 to 1.1

• Mutator for the comparison operators “<”, “<=”, “>” and “>=” to catch off-by-one problems
• Complete blacklist of reserved and built-in keywords that should not be used as identifiers (reduces invalid mutations)
• Metric for how many duplicated mutations were generated
• Switched to go/loader for type checking entire packages (reduces invalid mutations)
• Ignore mutations that cannot be compiled (reduces invalid mutations)
• Skipped mutations now count towards the total mutation counter and not the duplicated counter
• Support Go 1.10 and 1.11 and drop support for Go < 1.10
• Support MacOSX
