Scoped Headers

This release fixes issue#2. All includes of SheafSystem header files are scoped by "SheafSystem", that is they are of the form #include "SheafSystem/xxx.h" The build system copies all headers to source_tree_root/build/include/SheafSystem at build time and to installation_tree_root/include/SheafSystem at installation time so the scoped references will resolve correctly. Clients should use similar include statements and compiler option -I source_tree_root/build/include or -I installation_tree_root/include/SheafSystem.

This release also updates the README files to fix issue#3.

Fast Forward

This release includes updates for compatibility with C++11 (gcc 4.9.3, VS2015), Windows 10, CentosOs 6.x, Cmake 3.5, VTK 7.0, and recent versions of other prerequisites. It also incorporates a major revision of the build system to make it substantially easier to build.
