matchedDotOperatorCallOperation

[KronicDeth]

The matchedDotOperatorCallOperation rule implements the operator portion of #30. A subrule is noParenthesesOneArgument which implements part of #60, but not it's direct usage in matchedExpression as noParenthesesOneArgument is treated as an argument itself in matchedDotOperatorCallOperation (Alias.|> function argument).
