Create a function that accepts 3 parameters and checks for equality 
between any two of them. Your function should return True if 2 or 
more of the parameters are equal, and false is none of them are 
equal to any of the others.

Extra credit:
Modify your function so that strings can be compared to integers if they 
are equivalent. For example, if the following values are passed to your 
function: 6,5,"5" you should modify it so that it returns true instead 
of false. Hint: there's a built in Python function called "int" that will 
help you convert strings to Integers.
