Subject: [PATCH] added explicit to constructors to prevent implicit type
 conversions

for example, this will prevent "Token token = 47" because this is an
undesired implicit conversion from an integer, which would have been
allowed without the 'explicit' keyword on the constructor definition
for "Token(int column = -1)"
