Fixed a typo
Implemented functionality to convert minterms to boolean function
Also converts boolean function to 'Implementable Form' - see ConvertExpression
ImplementBooleanFunction also implemented
constructor corrected
Added ExpressionConvert example
fixed makeCompatible() in ExpressionConvert.py also.
