typeinfo - show variable data type

Typeinfo package has two commands, typeof and typenames.
typeinfo::typeof returns a data type of a value. If the
value are assigned to no type, it returns empty. Tcl is
a typeless language, I know the concept.  But Tcl has a
no way to distinguish  bytearray data from  string data. 
I took pains to do it, so I wrote this!!
typeinfo::typenames  returns  a list of registerd types.

Install:
      ./configure
      make 
      make install

Usage:
      package require Typeinfo
      
      typeinfo::typeof $var
	  typeinfo::typenames
