Package GoMathExecutor provides simple expression executor.
## Installation
`go get github.com/neonxp/GoMathExecutor`
## Usage
```
calc := executor.NewCalc()
calc.AddOperators(executor.MathOperators) // Loads default MathOperators (see: defaults.go)
calc.Prepare("2+2*2") // Prepare expression
calc.Execute(nil) // == 6, nil
calc.Prepare("x * (y+z)") // Prepare another expression with variables
calc.Execute(map[string]float64{
"x": 3,
"y": 2,
"z": 1,
}) // == 9, nil
