This app will be presented at the tutorial session at Sierra Wireless
Developer Day 2016.

GPIO 1 has been changed to an input with pullup to match the pullup on
the card itself.

The IoT card eeprom input YAML files have been updated based on review
feedback.
 * number the GPIOs from 1-4 instead of 0-3
 * unused GPIOs are configured as input with pull-up instead of input
   floating
 * vendor name changed to "Talon Communications"
 * serial numbers have been set to an empty string
 * miscellaneous corrections to properties such as card height

Also add sample input files for various existing IoT cards.

The gpioExpanderDemo application was used for basic system testing.
It doesn't belong in the standard mangOH system.

Patch1:
Changed name of the variables.
Btw this is how it is all connected:

This enables Legato to build doxygen and include a link to a mainpage
from another project.
The other system must define the following

export EXTERNAL_DOXYGEN_DEFINE = EXTERNAL_DOXYGEN_DEFINE
export EXTERNAL_DOXYGEN_ROOT = $(PROJECTX_ROOT)/apps/WiFi
and it must also have a doxygen page called "external_proj_mainpage"


These defines are defined in targetDefs.projectx and will be read by CMake.

framework/doc/Cmakelist.txt:
EXTERNAL_DOXYGEN_DEFINE
EXTERNAL_DOXYGEN_ROOT
and sets
CMAKE_EXTERNAL_DOXYGEN_ROOT

They are then transfered into the soon to be preproccessed
doxygen config files :
framework/doc/doxygen.implementation.cfg.in
framework/doc/doxygen.user.cfg.in

These doxygen configuration files are preprocessed by CMake
and enables basic variable expansion.
Please note that doxygen variables are very restrictive
and only the ones set with the variable ENABLED_SECTIONS
in the config file are available.

This all enables the usage of conditional (similare to ifdef) usage to
include/exclude text. Currently all that is done is a link from the
Legato main page to the other projects page
Example:
@cond EXTERNAL_DOXYGEN_DEFINE
@subpage external_proj_mainpage <br>
@endcond

Patch 2:
  -Added define for PA choice.

Patch 1:
  -Added wifiWebAp to list of apps to build for MangOH

Change-Id: I5ccb08358743973b91eadee0c0f975c3ba74f667

patch 1:
- Added variable that will be transfered by cmake into doxygen to be used to test.
- please note that only  ENABLED_SECTIONS variables are visible to doxygen.
- doing "make docs" in legato, will now detect and bring MangOH into the doxygen.

Change-Id: I4e5aeee4ffbfdc541e8fcfba2b6f02f4143e06b3

patch 3:
removed trailing space

patch 2:
- added -

patch 1:
- when building legato, it will also build and integrate MangOH wifi
- note that MANGOH_WIFI_ROOT is set by the build
