Returns the embedded SQLite library version as a number.

Arguments: There are no arguments for this method.
Return value: The number of the library version in use, perhaps 3007013.
Remarks: This method is similar to the libVersion method, returning a whole number rather than a dotted version string. The value returned by this method should be exactly equal to the the compile-time version Compile Time Version Constants constant.
Details The functionality of thelibVersionNumbermethod is similar to that of the SQLite sqlite3_libversion_number API.
