Changes in this release.
new "??" operator (currently a function called "bool" for testing purposes)
new "size_res" functions:
example:
us5 := resize (us6, us5);
where us5 and us6 are UNSIGNED. The parameter is named "size_res", and
similar functions are in numeric_std, fixed_pkg, fphdl_base_pkg, and fphdl_pkg.

Floating point base package has been completely redesigned.
1) base type is now "float"
2) There are now operators in the base package. These perform full IEEE
floating point
3) The types "float32", "float64", and "float128" (float, double float, and
extended float in C) are defined.
4) You can now perform operations and functions with different widths.
5) names of the base functions have been simplified to "add", "subtract", etc.
