This data mapper allows you to map external data into the
vtkDataArray.
This in turn allows you to interface with vtk without
repacking the simulatordata.

Clean up and implement a pimpl VtkRenderer to hide
redering implementation.

Replace core::StdVector3d with std::vector<core::Vec3d>

because eigen 3d vector array is aligned
by default so no special allocator is needed. See core::StdVector3d
for more details.

Remove IndiceArray from DataStructures

use std::vector instead and update methods accordingly.

See merge request !35

Rename and restructure files and directories.

See merge request !34

and naming of the export targets.
Issue #27

Also renmamed many unseen sm* class names.

Add _USE_MATH_DEFINES to the windows compile definitions.

Document the Gitlab MR process...

... because there are some tricky bits (rough edges) where testing is concerned.

See merge request !32

Also fix instances where normalized was used wrongly.
Thank @tansel for spoting these.

Fix warnings

This eliminates all of the warnings on Mac OS X 10.10. Please check the changes as in some cases there might be better ways to resolve the issue.

See merge request !26

Attempt a fix at compiler features.

CMake's `target_compiler_features` directive does not support
many compilers yet, especially on Windows. This results in
cryptic error messages. Just turn off Windows attempts at this.

Make the debug information a warning.

Fix errors

Fix build errors and test crashes (but not test failures).

See merge request !27

This does not fix test results, but does save significant
time on Mac OS X where crashes generate report files, which
is a slow process.

1. Do not assign variables to themselves.
   These values were already assigned at the top of the method.
2. Fix bad logic in conditional:
   a. Move inequality operator inside parentheses.
   b. Use a logical rather than a bitwise OR.

smDoubleBuffer was an unused class.
But its header and implementation files defined a class that is in use: smPipe.
So, remove smDoubleBuffer and rename the files.
