[tng-devel] tmath.is_swig_type fixed!

[Sebastian Wolff <sw@xxxxxxxxxxxxxxxxxxxx>]

The call of

A = tmath.Matrix( { {1,0}, {0,1} } );

should work now.

The reason was a mistake in

tmath.is_swig_type which did not return boolean, but integer

On Lua, the expression 'if (A)' is true if it is an integer (it is not 
equal to nil), but returns true or false if A is a boolean value. 
Therefore, tmath.Matrix(table t) always believed it got a table with 
Matrix objects inside...
