* declared intwidth, fracwidth, and is_signed UDPs * fix boolean type name in UDP definition * generate hwif fields with fixedpoint indices * make "counter" and "encode" properties mutualy exclusive with signed/fixedpoint * add signed/unsigned to hwif * improved fixedpoint error messages, added validation tests * added fixedpoint tests * fixedpoint/signed not allowed for signal components * added signed/fixedpoint UDP docs * handle single-bit fixedpoint numbers * fix too many positional arguments lint * changed spelling of fixedpoint to fixed-point * use "logic" in place of "unsigned logic" * split signed and fixedpoint docs, added examples * allow enums with is_signed=false * split signed and fixedpoint implementations * assorted nits picked * updated is_signed validation unit test
