If someone attempts to have both a versioned and non-versioned serialization
function, they will get a compile time error.
relates to improvements in #23
Also fixed a bug with some type traits that would erroneously return true if
an odd number of boolean variables were true when the desired behavior was to return
false if more than one boolean variable was true.
Need to revise the no matching serialization to properly fire if a type is specialized
but has both versioned and non-versioned functions of the specialization type.
