Set the analog Value of a pin. It will be output using PWM.
Objects can contain:
* `freq` - pulse frequency in Hz, eg. ```analogWrite(A0,0.5,{ freq : 10 });``` - specifying a frequency will force PWM output, even if the pin has a DAC
* `soft` - boolean, If true software PWM is used if available.
* `forceSoft` - boolean, If true software PWM is used even
**Note:** if you didn't call `pinMode` beforehand then this function will also reset pin's state to `"output"`
