// For example, if you were using an MCP I/O Port Expander with the Adafruit mcp library, you could create a triggerType function for a pin
// on the MCP device that is connected to ground through a pushbutton as such:
//
// boolean MCP_READ(int mcpPin) { return ( !mcp.digitalRead(mcpPin); ) }
// boolean MCP_READ(int mcpPin) { return ( !mcp.digitalRead(mcpPin) ); }
//
// And then simply pass MCP_READ to SpanButton as the triggerType parameter using any of the SpanButton constuctors:

// Alternatively, you can use a lambda function as the triggerType parameter, thus creating your function on the fly when instantiating a SpanButton:
//
// new SpanButton(23,[](int mcpPin)->boolean{ return ( !mcp.digitalRead(mcpPin); ) }
// new SpanButton(23,[](int mcpPin)->boolean{ return ( !mcp.digitalRead(mcpPin) ); });

// Note: If you create your own triggerType function, don't forget to perform any initialization of the "pin", or setup/configuration of a
// pin extender, etc., prior to instantiating a SpanButton that uses your custom function. HomeSpan cannot do this for you.
