1. Create a Counter factory with:

   • A private _value property initiated with 0.
   • A public getValue method.

   Initialize and assign it to a variable and make a call to getValue from outside printing the counter value;

2. Add to Counter:

   • A private _changeValueBy method to change it's value.
   • A public increment method that calls _changeValueBy;
   • A public decrement method that calls _changeValueBy;

   Initialize two counters and make subsequent calls to increment and decrement then compare values of each counter instance;
