Enhancements made to compile and destroy library files

Enhancements were added to the Makefiles to allows compiled and configured
library files to be clobbered, cleaned, and distcleaned.

The CPU architecture is also being detected in Macros.hh, which is used in
StdTypes.hh to type define the correct variables for bit sizes.

File: Build/StdMake/Makefile.app
--------------------------------
- Enhancements were added to support library compilation and deletion

File: Build/StdMake/Makefile.libs
---------------------------------
- Enhancements were added to support library compilation and deletion

File: .gitignore
----------------
- Files were changed to not include new library directories and allow header
  files to be included, but not their links

File: GramSchmidt_App/src/GramSchmidt.cc
----------------------------------------
- Changes made to test the CPU architecture detection

File: Utilities/libutldefs/header/Macros.hh
-------------------------------------------
- New file where common macro definitions will go that can be used across
  various programs. It currently defines a macro for the CPU architecture using
  the g++ compiler macros.

File: Utilities/libutldefs/header/StdTypes.hh
---------------------------------------------
- Type defines all data types in variables that easily determine their bit size
- This works for 32 and 64-bit architectures

File: Utilities/libutldefs/Makefile
-----------------------------------
- Addition of a Makefile to descend the directory structure

File: Utilities/libutldefs/src/Makefile
---------------------------------------
- Addition of a Makefile to descend the directory structure

File: Utilities/libutlmath/header/Vector.hh
-------------------------------------------
- Changes made to support the C++11 standard and fix a few comments

File: Utilities/libutlmath/src/Makefile
---------------------------------------
- Changes to support library compilation if a libxxx directory only contains
  header files and no source code files

File: Utilities/libutlmath/src/Vector.cc
----------------------------------------
- Fixed a compiler warning for assignment between different data types
