Grouped logog targets.

See this explanation:  http://randomascii.wordpress.com/2011/07/22/visual-c-debug-buildsfast-checks-cause-5x-slowdowns/

- modified test programm in order to test another example

- FileFinder.h
- FileTools.h
- TimeMeasurementBase.h
- quicksort.h

changes due to namespace changes in:
- PointVec.cpp
- Polygon.cpp
- AdjMat.cpp
- CRSMatrixReordered.cpp

- binarySearch
- class CPUTime
- class RunTime
- methods/functions from DateTools.{h,cpp}

changes in GeoLib and in SimpleTests folder results from changing the namespace

in order to make the name of libraries, namespaces and directories more consistent the Base directory is know named BaseLib

Conflicts:
	MeshLib/Elements/Element.cpp
	MeshLib/Elements/Element.h

added test application for mesh reading, fixed some bugs, reading and creating a mesh is working now; Mesh is (for now) a friend of Node, this should be fixed soon.

changed size_t to unsigned; included a few (yet unimplemented) methods for mesh-consistency checking

Integrate logog library for logging

- fixed some warnings regarding the sequence of attributes in header file and initializer list in constructor

git-subtree-dir: Base/logog
git-subtree-split: 9f14a8af27b0c2cfe4299d0b823798a0e3bb6198

added some basic functionality (get, add, etc.) and introduced an example finite element class for tetrahedra
