Release notes

| Released on 2015/01/05, GitHub Release Link

Parallel computing framework for FEM by using PETSc, which also includes
- Parallel input of partitioned mesh data.
- Parallel output of solutions by using pvtu data format.
New data structures for mesh properties are used everywhere replacing
Element's value member.
The penalty method to impose first-type boundary conditions was substituted
with a non-penalty method for LIS and Eigen linear solvers.
Support for multiple nodal variables is extended to the boundary conditions,
the sparsity pattern.
Passing of linear solver options from the project files is now possible.
The global matrix and global vector type of indices is consistent with the
linear solver library being used.

Added CMake option OGS_CPU_ARCHITECTURE, #858, downloadable binaries build by Jenkins should now run on more CPUs
Added CMake options for Boost, VTK and Eigen (OGS_LIB_BOOST, ...) to specify if libs are searched on the system first, then build them locally (Default), or you can specify to just use system libs (System) or force a local build (Local)
Added CMake options for enabling Clang sanitizer:
- OGS_ADDRESS_SANITIZER
- OGS_UNDEFINED_BEHAVIOR_SANITIZER
The zlib library is removed from ThirdParty directory.
A LIS solver interface using Eigen's sparse matrices is now available through
CMake option OGS_USE_EIGENLIS.
CMake configuration uses ccache if available.
