Fixing const-correctness in BP1
Changed CodingGuidelines to include clang-format information

helloBPWriter and timeBPWriter

Fix Variable.SetSelection(). heatTransfer adios2 writer is intentionally broken to keep to the intended API.

Using {} syntax for direct initialization of reference types in constructor
member initialization lists is broken on some compilers, even though it's valid
C++11 code.  Use () to ensure correctness.

added: 
./packages/format/bp1
./packages/profiling/iochrono
./packages/wan/dataman (for DataMan integration in ADIOS)

Will merge into groupless branch

Single variable example works. Moving on to time aggregation example.

Need to verify metadata footer

Added ADIOS1 Engine for writing with pre-installed ADIOS 1.x library. mpi dummy collision prevents building examples in nompi mode.

Added CopyToBuffer function to use std::copy 
Separating Metadata writes in Data and Metadata (Indices)
