expr

Golang rule engine, support logical expression

Support type: int string

Support operation: > < >= <= && ||

Support two inner funnction: in_array(1, []int{1,2,3,4}), ver_compare(x, ">", "10.1.1") with no nested

I believe it satisfy most filter scenarios using rule engine for logical expression.

Finally, Welcome contribution or requirement.

How to use it

	engine, err := NewEngine(v.expr)
	if err != nil {
		t.Error(err) 
	}
	result, err := engine.RunRule(v.control)

the ast parser using Golang go/ast and go/parser, rule can be update using engine.UpdateAst to avoid parse the rule each time. more demo please refer to the expr_test.go
