This is a template module for the ORFEO

Toolbox( It is designed to work with OTB >= 5.0
modular system. The module can be clone/copied in `OTB/Module/Remote` and
compiled along with other OTB modules. However, it is also possible to build it
as a standalone module.

This module is filled with a few templates to be used as a starting point for a
module with actual content. It contains the templates for:
* sources (`src` folder)
* includes and templated classes (`include` folder)
* application (`app` folder)
* a library (`cxx` source in `src` folder)
* headers and templated classes (`include` folder)
* a OTB Application (`app` folder)
* tests for C++ sources, applications and python wrappers (`test` folder)
This module also has its own continuous integration scripts (using Travis CI).

### Continuous Integration
This module contains default files to enable Continuous Integration on
* `travis-ci.yml` : this is the backbone of the CI process in Travis-CI, it
defines the different jobs to run, and their environment
* `ci.cmake` : this CTest script drives the build and test process.
* `` : this script is used on Windows to export variables from
`vcvarsall.bat` to the Git-Bash executor.
The `` starts with a Travis-CI badge, you can change it to match your
own module.
If you need to access data file from `OTB/Data`, you can tune the file
`ci.cmake` which will download them for you before building:
* `RM_GET_FULL_DATA`: this flag will download all files under `OTB/Data`
* `RM_DATA_PATTERNS`: this variable allows to download only the files you need.
Set this variable to a list of patterns (for instance
`Data/Input/QB_Toulouse_*.tif`). This method should be faster.

# the variable ${otb-module}_LIBRARIES only contains this library, which doesn't
# drag OTBApplicationEngine, so we need to add it explicitely.
