Created the DataTypeHistory and DataTypeZipper for Array nesting.
Fixed error printing for 'missing " at end of String'
Now we can have multiline strings delimeted by three " , like this: """
Scope now is a newtype
Now we compare Positions correctly.
Now we have a 'fillLex' function that assigns the 'defaultPosn' and the 'a' we give it.
Fixed Acces a little
Now the statement 'Record' and 'Union' have lower-case words, like 'record' and 'union'
Access and DataTypeHistory imports/exports
Now we store the Lexeme of the DataType and the scopeStack in Symbol.
At the end of finding definitions we 'fixDataTypes',
it points the dataType field of the Symbols to the real DataType, instead of
it just being an Identifier of the type.

We may have a bug in here. Check comments near the call of 'fixDataTypes'.
