If it find this character combo, we must make sure it's not the closing symbol for a block comment (which can, in fact, start with multiple %% characters). If it is the close to a block comment, then it's not a line comment.

Parameters:

line - line to isLineComment for line comment

closingBlockCommentSymbol - null if we're not in a block comment; the symbol, if we are.

Returns:

true if this is a line comment, false if it's not

Throws:

java.lang.IllegalArgumentException - if passed a null line
